CQM6RT MCCB thermostatique et magnétique réglable - Fabricant OEM
Le CQM6RT MCCB fournit une protection réglable contre les surcharges et les courts-circuits dans sa plage 32–1250A publiée. La spécification doit tenir compte de la tension du système, de la charge, de la coordination des conducteurs, du courant de défaut présumé et des règles applicables, et non pas uniquement de la valeur en ampères.
Vue d'ensemble du produit
CQM6RT est un disjoncteur thermomagnétique destiné aux applications de distribution et de protection en courant alternatif 400/415V. Sa gamme publiée s’étend de 32 à 1250A, avec des options 3P / 4P. Le choix dépend de la conception complète du système électrique, notamment du niveau de court-circuit, de la coordination, de l’ampacité des conducteurs, des conditions d’encapsulation et des réglementations locales.
La spécification produit fournie fait référence aux normes IEC/EN 60947-1, IEC/EN 60947-2, IEC/EN 60947-3 et IEC/EN 60947-4, ainsi qu’aux normes GB/T 14048.1, .2, .3 et .4. Ces références normatives ne constituent pas, à elles seules, une certification pour une commande particulière.
Principales caractéristiques
Applications typiques
Les applications typiques comprennent les alimentateurs industriels et les circuits de moteurs pour lesquels la coordination en champ nécessite des réglages de déclenchement ajustables. Il s’agit de contextes d’évaluation et non de homologations universelles. Vérifiez avec précision le boîtier, la tension, la capacité de coupure, le déclencheur, les accessoires et la méthode d’installation avant toute spécification.
Demandes d’admission et guide de sélection
Utilisez les valeurs CQM6RT vérifiées ci-dessous pour établir une liste restreinte, puis validez le circuit complet. Le calibre d’un disjoncteur modulaire (MCCB) ne remplace pas les calculs des conducteurs, l’analyse du courant de défaut, l’examen de la coordination ou les exigences locales d’installation.
| Point de sélection | Référence CQM6RT | Ce que le projet doit confirmer |

| Courant nominal | 32–1250A | Courant de conception, ampacité des conducteurs, mode d’installation, température et regroupement |
| Tension | AC 400/415V | Système d’alimentation et dimensionnement des équipements |
| Pôles | 3P / 4P | Conducteurs sous tension et traitement du neutre |
| Voyage / protection | Imagerie thermique IR et imagerie magnétique IM réglables | Profil de charge, réponse aux défauts et coordination |
| Capacité de rupture | Classes C/S/M/H jusqu'à 75kA, selon le châssis et la configuration commandée | Courant de court-circuit prévisionnel au point d’installation |
Protection fixe vs réglable
Un dispositif thermomagnétique fixe peut convenir à une conception stable, tandis qu’un déclencheur réglable peut faciliter la coordination lorsque l’étude de projet nécessite des réglages sur site.

Disjoncteur modulaire (MCCB) vs Disjoncteur miniature (MCB)
An MCCB is normally evaluated for higher current, fault duty or accessory flexibility; an MCB may be more suitable for compact final circuits.

Icu vs Ics
The saved data for CQM6RT lists C/S/M/H classes up to 75kA, according to frame and ordered configuration. Match the declared duty to the prospective short-circuit current and continuity objective.

Guide d'achat
- State the exact model: CQM6RT.
- Provide frame and rated current within the published range: 32–1250A.
- Confirm poles: 3P / 4P.
- Specify the trip unit or protection function: adjustable thermal Ir and magnetic Im.
- Provide system voltage, frequency, application, expected fault level, destination market and quantity.
- List required accessories, terminals, documents and any approved OEM/ODM marking or packaging requirements.
Examens d’installation et de coordination
- Use the exact model drawing and instructions; do not infer terminal positions, supply direction or accessory compatibility from another MCCB.
- Verify conductor material and cross-section against the circuit calculation, terminal data, temperature and grouping.
- Confirm Icu/Ics or DC fault duty, upstream/downstream coordination, enclosure conditions, altitude and clearances.
- Installation, isolation, testing and maintenance must be performed by qualified personnel under applicable rules.

CQM6RT Product FAQ
What is the CQM6RT MCCB used for?
The CQM6RT is specified for adjustable overload and short-circuit protection in AC 400/415V systems within the published 32–1250A range. Suitability depends on the fault study, conductor coordination, enclosure and local rules.
How does the CQM6RT molded case circuit breaker work?
The protection mechanism responds to the fault conditions stated for this model: adjustable overload and short-circuit protection. Trip behaviour, settings and interruption duty must be checked against the ordered frame and product instructions.
How do I choose the CQM6RT rated current and poles?
Start with the design current and conductor calculation, then choose a published current within 32–1250A and poles from 3P / 4P. Neutral treatment, fault level, ambient conditions and coordination also need review.
What breaking capacity should I check on the CQM6RT?
Use the declared C/S/M/H classes up to 75kA, according to frame and ordered configuration for the exact frame, voltage and configuration. The prospective short-circuit current at the installation point must be within the applicable duty; a larger ampere value alone is not a selection rule.
Can the CQM6RT replace an MCB or an earth-leakage device?
An MCCB is not automatically a like-for-like replacement. The CQM6RT provides adjustable overload and short-circuit protection; residual-current protection, DC interruption, adjustable settings and other functions must be confirmed separately from the project requirement.
How should the CQM6RT be installed and tested?
Use only the exact model drawing, terminal identification and accessory instructions. A qualified person should verify isolation, conductor size, torque, clearances, settings, fault duty and functional tests before energising the circuit.
Confirm the Right CQM6RT Configuration
Send the frame, rated current, poles, protection function, system voltage, expected fault level, destination market and quantity. CHAC will review the request against the published model range.
