Fabricante OEM de disyuntores moldeados (MCCB) estándar CQM6
El CQM6 MCCB provides overload and short-circuit protection within its published 16–1600A range. Specification should follow the system voltage, load, conductor coordination, prospective fault current and applicable rules—not the ampere value alone.
Descripción del producto
CQM6 is a mccb breaker for AC distribution and protection applications. Its published range covers 16–1600A with 2P / 3P / 4P, depending on frame; CQM6-1600: 3P options. Selection depends on the complete power-system design, including fault level, coordination, conductor ampacity, enclosure conditions and local rules.
The supplied product specification references IEC/EN 60947-1, IEC/EN 60947-2, IEC/EN 60947-3 and IEC/EN 60947-4, together with GB/T 14048.1, .2, .3 and .4. These standard references do not, by themselves, establish certification for a particular order.
Características clave
Aplicaciones típicas
Typical applications include commercial, industrial and infrastructure distribution or motor circuits. These are evaluation contexts rather than universal approvals. Confirm the exact frame, voltage, breaking duty, trip unit, accessories and installation method before specification.
Guía de Solicitudes y Selección
Use the verified CQM6 values below to create a shortlist, then validate the complete circuit. An MCCB rating does not replace conductor calculations, fault-current analysis, coordination review or local installation requirements.
| Punto de selección | CQM6 reference | Lo que el proyecto debe confirmar |
|---|---|---|
| Corriente nominal | 16–1600A | Design current, conductor ampacity, installation method, temperature and grouping |
| Voltaje | AC 400/415V; CQM6-1600 also lists 660/690V configurations | Sistema de suministro y capacidad nominal de los equipos |
| Polacos | 2P / 3P / 4P, depending on frame; CQM6-1600: 3P | Live conductors and neutral treatment |
| Trip / protection | thermal-magnetic trip | Load profile, fault response and coordination |
| Capacidad de corte | C/S/M/H/L classes, with Icu up to 100kA for the listed CQM6-1600 660/690V configurations; verify the exact frame and voltage | Prospective short-circuit current at the installation point |
Fixed vs Adjustable Protection
A fixed thermal-magnetic device can suit a stable design, while an adjustable trip unit may help coordination when the project study requires field settings.
Trip Coordination

MCCB vs MCB
An MCCB is normally evaluated for higher current, fault duty or accessory flexibility; an MCB may be more suitable for compact final circuits.
Current & Fault Duty

Icu vs Ics
The saved data for CQM6 lists C/S/M/H/L classes, with Icu up to 100kA for the listed CQM6-1600 660/690V configurations; verify the exact frame and voltage. Match the declared duty to the prospective short-circuit current and continuity objective.

Un estricto sistema de control de calidad garantiza que cada producto cumpla con los estándares mundiales.
¿Qué podemos personalizar?
For CQM6 projects, CHAC can review private-label marking, packaging, approved appearance options, published 16–1600A electrical configurations and technical-document requirements. Requests outside the published range are subject to engineering evaluation, testing, minimum order quantity and project feasibility.

CQM6 Product FAQ
What is the CQM6 MCCB used for?
The CQM6 is specified for overload and short-circuit protection in AC systems at the voltage listed for the ordered frame within the published 16–1600A range. Suitability depends on the fault study, conductor coordination, enclosure and local rules.
How does the CQM6 molded case circuit breaker work?
The protection mechanism responds to the fault conditions stated for this model: 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 CQM6 rated current and poles?
Start with the design current and conductor calculation, then choose a published current within 16–1600A and poles from 2P / 3P / 4P, depending on frame; CQM6-1600: 3P. Neutral treatment, fault level, ambient conditions and coordination also need review.
What breaking capacity should I check on the CQM6?
Use the declared C/S/M/H/L classes, with Icu up to 100kA for the listed CQM6-1600 660/690V configurations; verify the exact frame and voltage 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 CQM6 replace an MCB or an earth-leakage device?
An MCCB is not automatically a like-for-like replacement. The CQM6 provides 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 CQM6 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 CQM6 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.
