2 Unitas Extractibilis Cistella - usque ad 400 A, pro Variabilibus Frequentiis Ductoribus et Maioribus Alimentatoribus
2 unit is the largest standard drawer in the range and the one specified when a variable frequency drive, a large starter or a 400A feeder has to sit in a withdrawable compartment. It occupies two module positions, which gives it the depth, ventilation path and terminal space that a drive genuinely needs.
WHY A VFD NEEDS THIS SIZE
A variable frequency drive is a heat source, not just a switching device. It needs airflow across its heatsink, it needs clearance from adjacent equipment, and it needs terminal space for motor cable with screening properly terminated. Put a drive in an undersized compartment and three things happen in sequence: the drive derates, then it trips on over-temperature during the hottest part of the day, and then the customer concludes the drive brand is unreliable. The compartment was the problem.
In a Gulf switchroom running at 50–55 C against an IEC reference of +40 C, this is not a marginal effect. Drive derating must be calculated for the actual internal temperature, and the ventilation arrangement has to be part of the design rather than something added later.
EMC IS PART OF THE DESIGN
Drives generant interference conducta et radiata. Compartmentum unitatis 2 sustinet terminationem scuti 360 graduum pro cavo motoris, segregationem wiring potentiae et controlis, et provisionem pro filtris input et reactoribus output ubi longus est cursus cavi motoris. In projectis signatis CE sub Directiva EMC hoc non est optionale, et est defectus communis in tabulis localiter constructis.
FACTORY BUILT AND TESTED
Confectum, connexum, notatum et singillatim probatum ad tuum programmam alimentatoris, cum marca dispositivi et impulsum ad tuam specificam, delatum cum certificato probationis ordinariae. Aut suppeditatum ut kit CKD cum carcasse, contactibus isolantibus, mechanismo racking, interlock, manubrio, conectori secundario, fasciculo modulari praeciso, schemate confectionis et tabula momentorum.
INTERCHANGEABLE, AND SPARE-ABLE
Idem isolatio systema, ternarius positio mechanismus et interlock schemea ut reliquae seriei, eadem schematis revisio per tempus servata. Magnus drive feeder exacte ubi hot spare drawer sibi pretium reddit, quia drive defectus in principalis processus linea in amissa productione, non in unitatis pretio, mensuratur.
Applicationes principali
- Variabilis frequentialis drive feeders in motor control centris — principalis causa cur haec magnitudo exstat.
- Motor starters ab circiter 90 kW usque ad 200 kW.
- Distribution feeders usque ad 400A in withdrawable tabulis.
- Magni soft starter feeders cum bypass et reactor.
- Principales processus drives: molae motores, magni convectores, frangentes, alti pressionis pumps, ID et FD fans.
- Sectio actionum principalium in fabricis cementi, minerarum, ferri, papyri et sacchari.
- Alimentaria potenter potentia in stationibus desalinisationis et pompationis aquae.
- District cooling et magnae chiller plant compressor feeders.
- Sub-principales feeders ab principalis tabula ad inferiorem MCC.
CONFIGURATIONES TYPOLOGICAE
VFD feeder cum MCCB, impulsum, reactor autem vel filtrum input et dispositio bypasse; magnus stellae-delta aut mollis incitatio feeder; 400A distributio feeder cum mensura et protectione electronica; magnus direct-on-line starter cum relais protectionis motoris electronici.
WHY BUYERS SPECIFY IT
Quia maximi feeders sunt qui, si deficiant, totam fabricam sistunt. Feeder VFD extrahibilis binarius cum altero in deposito conversio est multidiurnae substitutionis impulsum in simplicem commutationem, dummodo alter in deposito ordinatus sit — quod est sermo quem aedificator tabularum iam in statu offerendi habere debet, non post primam defectionem.
Congruentia Regionalis
- Medius Oriens: desalinatio, refrigeratio districtus et fabricae petrochimicae magnos impulsus continue in altis temperaturis ambientibus agunt. Derating pro vera temperatura switchroom declaranda est in submissis, et approbationes SASO SABER et utilitatum pro Arabia Saudita, UAE, Qatar, Kuwait et Oman suffragandae sunt.
- Africa: mining and cement main drives. Grid instability makes drive input protection and ride-through configuration important, and remote sites make a spare unit a practical necessity.
- Russia and CIS: 380 V / 220 V, EAC under TR CU 004/2011 and TR CU 020/2011, cold-start considerations for outdoor-adjacent switchrooms.
- Eastern Europe: 400 V, CE under LVD and EMC to EN 61439-2, with EMC compliance for drive feeders taken seriously by inspectors.
Non idoneus pro
Drives above the compartment rating, which need a dedicated fixed cubicle with its own ventilation. Fixed-type boards such as GGD, XL-21 and JXF.

Nota
Hanc magnitudinem specificare pro quolibet alimentatore variabilis frequentiae. Motor necessitat aerem transversum per suum dissipatorem caloris, spatium inter se et apparatus adiacentes, et spatium terminale pro cable electrico motoris; cellula parva causat reductionem potentiae et interruptionem propter nimiam caliditatem, quae erronee imputatur motori.
SUPPLIED READY TO INSTALL - THE HARD PART IS ALREADY DONE
Un cassetto non est un cassa con un interruttore in ea. Le alliniationes de contactus, le geometria del interblocco a tres positiones e le engagement del secundari connexione sunt le partes de un cassetto estraibile que le officinas local face mal, e un cassetto male alliniate es lo que se converte in un contactu ardentie duo annos post. Nos fornimos le unitates montate, cablate e probate, ita que vostre officina construe un armario — non depura un mecanismo.
1. UNITATES FUNCTIONALI CONSTRUCTE SECUNDO VOSTRE PROGRAMMA
Invia nos le programma del alimentator e nos construe le cassettes secundo illo: distributione, directe in linea, stella-delta, starter molle, VFD, inversion. Marca del dispositivo secundo vostre specificationes. Cata unitate es fornite con cables connectite a terminales, etiquettate e probate individualmente.
2. INTERCAMBIABILITATE GARANTITE TRANSVERSALMENTE LE PARTITAS
Dimensiones standard de los módulos se mantienen en la misma revisión de plano año tras año. Un cajón de 1 unidad pedido hoy encaja en un armario que usted construyó hace tres años. Esta es la única razón por la que los consultores especifican un sistema estandarizado, y es donde un diseño de cajón propietario interno genera costos adicionales para el cliente más adelante.
3. KITS DE CAJONES CKD PARA MONTAJE LOCAL
Si prefiere montar internamente, le suministramos el cajón como kit: carcasa, contactos aislantes, mecanismo de desplazamiento, interbloqueo, mango, conector secundario y arnés de cableado, junto con el plano de montaje y una hoja de pares de apriete y calibración. El arnés de cableado modular precortado por sí solo elimina aproximadamente el 30 % de la mano de obra de montaje in situ comparado con cortar y empalmar cada cable individualmente.
4. CAPACITACIÓN EN EL MECANISMO
Alineación, verificación de presión de contacto, verificación de tres posiciones, prueba de función de interbloqueo y verificación de fuerza de desplazamiento — impartida en su propio banco de trabajo, con sus propias unidades, ya sea in situ o mediante sesión por video.
5. ESTRATEGIA DE CAJONES DE REPUESTO Y PIEZAS DE REPUESTO
Quote the spare drawer set with the main order. A hot spare drawer is what lets a plant restore a feeder in minutes instead of hours, and on EPC projects it is often the reason a withdrawable board was specified in the first place. We keep the design available so spares remain buyable for the life of the installation.
6. DOCUMENTATION FOR YOUR SUBMITTAL
Routine test certificate per unit, device certificates, wiring diagram, drawer schedule and part list. Formatted so it drops straight into your IEC 61439 verification file.
7. POST-VENDITIONEM
24-hour technical response, 12 months from commissioning or 18 months from shipment, spare contact and interlock parts held to the same revision.
8. CONDITIO COMMERCIALIS
FOB, CFR, CIF, DDP, Ex-Works. Mixed loading with cabinets and components. Trade Assurance, T/T, L/C. Sample units accepted before volume.
QUALITY CONTROL - EVERY DRAWER TESTED AS A UNIT
A withdrawable board fails at the interface, not in the middle of a component. Contact pressure, alignment and interlock geometry decide whether the drawer is still healthy after a thousand operations, and none of that is visible after the door is closed. Each unit is therefore tested as a complete assembly before it leaves the line.
DIMENSIONAL AND MECHANICAL CHECKS - 100%
1. Shell dimensions and squareness against the module drawing, so interchangeability with earlier batches is real and not assumed.
2. Isolating contact alignment and engagement depth verified with a gauge; contact pressure measured against specification.
3. Silver plating thickness on primary and secondary contacts checked on batch samples.
4. Three-position operation - Connect, Test, Disconnect - each position confirmed to latch positively with correct indication.
5. Functio interlock — cista non potest extrahi dum dispositio clausa est, nec dispositio claudere potest inter positiones definitas. Probata in utroque directione.
6. Vis operativa extrahendi mensurata et annotata; mechanismus rigide reicitur, non adiustatur in loco clientis.
7. Ordo contactuum terrae verificatus — contactus terrae primum efficiendus est et postremo interrumpendus, antequam et postquam contactus potentiae efficiuntur.
8. Durabilitas mechanica probata ad 100 000 cycli in exemplaribus testis typi.
CONTROLES ELECTRICI — 100%
9. Connexiones ad schemam unitatis verificatae; ferrulae, strictura terminalium et notatio inspectae.
10. Dispositio pinorum plagulae secundariae circuitu per circuitum verificata.
11. Examen dielectricum sustinendi ad tensionem nominalem testis per unum minutum, et resistentia insulationis mensurata et annotata.
12. Examen functionale logicae alimentatoris — ordo incipientis, parametri relectorum protectionis, indicatio et, ubi adfecta est, communicatio.
Quod Accipis
Certificatum examinis routine singularis continens numerum seriale unitatis, schemata cistulae, diagramma connexionum, certificata instrumentorum, et probationes typi systematis cistulae ad comprobationem dossiers IEC 61439.
TRACEABILITAS ET RESERVATAE
Omnis unitas numeratur secundum revisionem suae imaginis. Cum post quinque annos substitutum ordinaveris, cistula quae advenit est ea quae convenit. Exemplaria unitatum pro experimentis aptationis ante productionem massivam suppeditantur, et inspectio a tertio parte acceptatur si petatur.
