Puntos clave de selección
Aplicaciones típicas
Evaluate CQM5HU for AC distribution equipment within its documented voltage, fault-current and installation limits. A magnetic-only version needs a separately coordinated overload solution where overload protection is required.
Guía de Solicitudes y Selección
| Elemento de selección | CQM5HU configuration | Qué verificar |
|---|---|---|
| Marco y actual | 320 frame: 63–320A; 630 frame: 250–630A in listed steps | Check the actual available current and mechanism combination. |
| Capacity at 800V AC | 320 frame: 50kA; 630 frame: 65kA; Ics = Icu | Use the capacity for the operating voltage. |
| Capacity at 1140V AC | 320 frame: 15kA; 630 frame: 20kA; Ics = Icu | Do not carry the higher 800V values into an 1140V design. |
| Release options | Magnetic only or thermal-magnetic | Choose thermal-magnetic when integral overload and short-circuit protection are both needed. |
Use these checks to compare the protection function, configuration and related CHAC products before specifying CQM5HU. Related products are selection alternatives or system components, not automatic replacements.
Select breaking capacity at the actual AC voltage
CQM5HU has different short-circuit ratings at 800V and 1140V.
Confirm temperature conditions and the trip function
The operating data calls for derating above 40°C.
Compare CQM5NEZ for the required function
El disipador de circuito moldeado CHAC CQM5NEZ DC está disponible con unidades de parada magnética o térmica-magnética para circuitos de 1500 V CC. Seleccione una versión térmica-magnética cuando se requieran protección contra sobrecarga y cortocircuito. Los enchuferes de 350 A y 630 A cubren corrientes nominales de 63 A a 630 A, con una capacidad de desconexión determinada por el enchufe y la versión M/H.
Compare PXD6-125 for the required function
The CHAC PXD6-125 isolator provides electrical isolation and ON/OFF indication for terminal distribution assemblies. Choose the pole arrangement and rated current for the supply system, with AC-22A utilization and ratings up to 125A.
Need Help Specifying CQM5HU?
Send the circuit requirements, selected configuration, destination market and quantity for a model-specific review.
Select breaking capacity at the actual AC voltage
CQM5HU has different short-circuit ratings at 800V and 1140V. State the network voltage and calculated fault current together in the inquiry. Frame size alone cannot determine whether the breaker meets the installation fault level.
Confirm temperature conditions and the trip function
The operating data calls for derating above 40°C. Provide the actual enclosure temperature and installation conditions for review, and identify whether a magnetic-only or thermal-magnetic release is required. Neither a larger frame nor a larger trip setting substitutes for a coordination study.

CQM5HU Product FAQ
What do Icu and Ics mean on an MCCB?
Icu is the rated ultimate short-circuit breaking capacity and Ics is the rated service breaking capacity under the specified test conditions. Compare them at the actual operating voltage. CQM5HU lists Ics equal to Icu for the published frame/voltage combinations.
Can I use the 800V breaking capacity at 1140V?
No. CQM5HU-320 lists 50kA at 800V but 15kA at 1140V; CQM5HU-630 lists 65kA and 20kA respectively. Check the value for the actual system voltage.
Does a magnetic-only MCCB protect against overload?
A magnetic-only release does not provide the thermal overload function. Select the thermal-magnetic CQM5HU option when both protections must be integral, or provide an appropriately coordinated external overload solution.
How do I choose the CQM5HU current rating?
Start with load current and conductor capacity, then check trip function, enclosure temperature and protection coordination. Use an available current step within the chosen frame; frame size alone is not the circuit protection setting.
Can I copy a cable size from the CQM5HU table?
Treat the conductor table as a product reference. Final sizing also depends on installation method, conductor material, temperature, grouping, voltage drop, short-circuit duty and local rules. Check terminal compatibility and the model-specific torque.
What should a distributor specify when ordering CQM5HU?
State frame, rated current, operating voltage, breaking-capacity version, trip function and accessory voltages. Include drawings, destination-market documents, quantity and marking requirements; approve the exact configuration before a repeat order.
Specify the Right CQM5HU Configuration
Send CHAC your required configuration, application, destination market and estimated quantity. We will review the requested specification and provide the relevant technical documents and commercial proposal.
