قاطع دائرة مصبوب إلكتروني من سلسلة CQM5E
ال CQM5E MCCB provides overload, short circuit and optional ground-fault protection within its published 10–800A range. Specification should follow the system voltage, load, conductor coordination, prospective fault current and applicable rules—not the ampere value alone.
Product Overview
CQM5E is a electronic MCCB for AC 380/400/415V and AC 660/690V distribution and protection applications. Its published range covers 10–800A 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 60947-1 and IEC 60947-2 as the applicable standard reference. No certification claim is added beyond the model record.
Key Features
Typical Applications
Typical applications include commercial and industrial distribution or motor circuits that benefit from adjustable electronic protection. These are evaluation contexts rather than universal approvals. Confirm the exact frame, voltage, breaking duty, trip unit, accessories and installation method before specification.
Applications and Selection Guide
Use the verified CQM5E 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.
| Selection point | CQM5E reference | What the project must confirm |
|---|---|---|
| Rated current | 10–800A | Design current, conductor ampacity, installation method, temperature and grouping |
| جهد كهربائي | AC 380/400/415V and AC 660/690V | Supply system and equipment rating |
| أقطاب | 3P / 4P | Live conductors and neutral treatment |
| Trip / protection | electronic trip settings | Load profile, fault response and coordination |
| Breaking capacity | 20/70/85/100kA Icu and 10/50/65/75kA Ics values by frame and voltage | Prospective short-circuit current at the installation point |
Electronic vs Thermal-Magnetic Trip
Electronic trip units can provide adjustable thresholds and additional monitoring functions. Confirm the actual setting range, auxiliary supply and coordination study for the ordered model.

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
Compare MCCB and MCB →
Icu vs Ics
The saved data for CQM5E lists 20/70/85/100kA Icu and 10/50/65/75kA Ics values by frame and voltage. Match the declared duty to the prospective short-circuit current and continuity objective.

Ordering Guide
- State the exact model: CQM5E.
- Provide frame and rated current within the published range: 10–800A.
- Confirm poles: 3P / 4P.
- Specify the trip unit or protection function: electronic trip settings.
- 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.
Installation and Coordination Checks
- 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.

2.1 Motor Operating Mechanism
Schematic Diagram
Function
Suitable for remotely closing, tripping (resetting) the circuit breaker,and for automated applications.
Position indication for O (OFF), I (ON), and TRIPPED.
Enables free trip operation of the circuit breaker.
Allows manual or automatic closing and opening of the circuit breaker.
Automatic closing or tripping can be achieved using momentary pulse signals or maintained signal control.
Reliable closing and tripping of the circuit breaker is ensured only when the control voltage is **≥85% and ≤ 110%** of the rated control
voltage (Un).

Function
Employs a unique design and transmission mechanism to perform circuit breaker Closing, Tripping (Reset), and Opening operations via handle rotation.
Features isolated position indication.
Clear position indications: O (OFF), I (ON), and TRIPPED
The breaker in the OFF position accepts 1-3 padlocks (Φ5-8mm), preverhting inadvertent closure and locking compartment access.
In the ON (closed) position, handle rotation mechanically prevents compartment door opening.(For emergency door access, use the handle’smanual override release).
Standard shaft length: 150mm.

CQM5E Product FAQ
What is the CQM5E MCCB used for?
The CQM5E is specified for overload, short circuit and optional ground-fault protection in AC 380/400/415V and AC 660/690V systems within the published 10–800A range. Suitability depends on the fault study, conductor coordination, enclosure and local rules.
What does the electronic trip unit do in the CQM5E?
The electronic trip unit processes current signals and provides the adjustable protection functions stated for the model. Confirm the available long-time, short-time, instantaneous, ground-fault, auxiliary-power and communication options for the ordered configuration.
How do I choose the CQM5E rated current and poles?
Start with the design current and conductor calculation, then choose a published current within 10–800A and poles from 3P / 4P. Neutral treatment, fault level, ambient conditions and coordination also need review.
What breaking capacity should I check on the CQM5E?
Use the declared 20/70/85/100kA Icu and 10/50/65/75kA Ics values by 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 CQM5E replace an MCB or an earth-leakage device?
An MCCB is not automatically a like-for-like replacement. The CQM5E provides overload, short circuit and optional ground-fault protection; residual-current protection, DC interruption, adjustable settings and other functions must be confirmed separately from the project requirement.
How should the CQM5E 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 CQM5E 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.
