Descripción del producto

CQM6L is a earth leakage circuit breaker for AC 400/415V distribution and protection applications. Its published range covers 10–1250A frame range; verify ordered In with 3P / 4P options. Selection depends on the complete power-system design, including fault level, coordination, conductor ampacity, enclosure conditions and local rules.

The saved model record lists IEC/EN 60947 and GB/T 14048 references listed on the page as the applicable standard reference. No certification claim is added beyond the model record.

Overcurrent vs Earth-Leakage Protection

An MCCB's overcurrent function does not replace residual-current protection. Select leakage sensitivity, delay and waveform type from the verified model data and project rules.

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.

CQM6L Product FAQ

What is the CQM6L MCCB used for?

The CQM6L is specified for overload, short circuit and adjustable earth-leakage protection in AC 400/415V systems within the published 10–1250A frame range; verify ordered In range. Suitability depends on the fault study, conductor coordination, enclosure and local rules.

How does residual-current protection work in the CQM6L?

The residual-current function monitors imbalance associated with earth leakage and trips at the selected sensitivity or delay. The waveform type, threshold, time delay, earthing arrangement and local rules must be confirmed for the exact configuration.

How do I choose the CQM6L rated current and poles?

Start with the design current and conductor calculation, then choose a published current within 10–1250A frame range; verify ordered In and poles from 3P / 4P. Neutral treatment, fault level, ambient conditions and coordination also need review.

What breaking capacity should I check on the CQM6L?

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 CQM6L replace an MCB or an earth-leakage device?

An MCCB is not automatically a like-for-like replacement. The CQM6L provides overload, short circuit and adjustable earth-leakage protection; residual-current protection, DC interruption, adjustable settings and other functions must be confirmed separately from the project requirement.

How should the CQM6L 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 CQM6L 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.
