CQAX2 Series Shunt Trip + Auxiliary Switch
The CQAX2 shunt trip auxiliary switch is specified for combined shunt release and auxiliary switch. Published data includes AC 230V / DC 110V signal circuits; Ui 415V and shunt operating range 160–260V. Confirm the accessory interface, control circuit, wiring and destination-market requirements before ordering.
Product Overview
CQAX2 is a shunt trip auxiliary switch for low-voltage panel and breaker accessory systems. The summary below uses the published model record; it does not replace the complete drawing, wiring instructions or project design review.
Combined shunt release and auxiliary switch. shunt operating range 160–260V is the published electrical reference. Compatibility, contact logic and installation details must be confirmed for the exact ordered version.
Key Features
Typical Applications
Use it where a compatible breaker must be tripped from a remote control or emergency circuit. Confirm the control voltage, trip logic, accessory interface and safe isolation procedure; a shunt release is not an undervoltage release.
Applications and Selection Guide
Use the product-specific values below as a shortlist, then validate the complete circuit and mechanical interface. An accessory rating alone does not establish compatibility with every breaker, panel or control system.
| Selection point | CQAX2 reference | What the project must confirm |
|---|---|---|
| Primary function | combined shunt release and auxiliary switch | Confirm the required signal or protection function before ordering |
| Electrical reference | AC 230V / DC 110V signal circuits; Ui 415V | Match the project control or supply circuit |
| Rating / operating window | shunt operating range 160–260V | Use the published range; do not infer missing ratings |
| Interface | for compatible breaker accessory interface | Verify the compatible breaker, panel, base or rail interface |
| Wiring | 1 × 2.5mm² conductor reference | Final conductor and protection selection follows the project design and local rules |
| Documents | IEC 60947-5-1 | Request the exact drawing and applicable compliance documents for the ordered version |
Function and signal path
Combined shunt release and auxiliary switch. Confirm whether the circuit needs status feedback, fault alarm, remote trip or voltage release.
Control-circuit fit
AC 230V / DC 110V signal circuits; Ui 415V. Match the control voltage and operating window to the project circuit; never assume a nearby rating is interchangeable.
Mechanical interface
for compatible breaker accessory interface. Confirm breaker family, rail/base or panel interface, clearances and maintenance access.
Wiring and documentation
1 × 2.5mm² conductor reference. Request the exact drawing and installation document for the ordered configuration.
Ordering Guide
- Specify the exact model and accessory function: CQAX2, combined shunt release and auxiliary switch.
- State the control/supply voltage and any required operating window.
- Confirm the compatible breaker family, panel, base or DIN-rail interface.
- Provide quantity, destination market, wiring details and required technical documents.
- Ask CHAC to verify any non-standard marking, packaging or configuration request before production.
Installation and Coordination Checks
- Use the exact product drawing and installation instructions for the ordered configuration.
- Verify voltage, conductor, terminal, enclosure, clearances and maintenance access.
- Check the accessory’s signal or trip logic against the control circuit and upstream/downstream protection.
- Installation, testing and maintenance must be carried out by qualified personnel under applicable rules.

CQAX2 Product FAQ
What is the CQAX2 used for?
The CQAX2 provides remote shunt tripping for a compatible breaker system. It is selected as a control accessory, not as a standalone overcurrent device.
What is the difference between a shunt trip and an undervoltage release?
A shunt trip is generally energize-to-trip, while an undervoltage release responds to a loss or reduction of its control voltage. Confirm the required trip logic for the project.
What control voltage does the CQAX2 use?
The published reference is AC 230V / DC 110V signal circuits; Ui 415V, with shunt operating range 160–260V. Do not substitute another coil voltage without confirming the exact model.
Which breaker is compatible with the CQAX2?
The product record specifies a compatible for compatible breaker accessory interface. Confirm the breaker model, interface and accessory combination from the drawing.
Can a shunt release provide overload protection?
No. It trips a compatible breaker remotely; overload and short-circuit protection come from the breaker and must be selected separately.
What wiring is listed for the CQAX2?
The published conductor reference is 1 × 2.5mm² conductor reference. Final wiring, isolation and control-circuit protection must follow the project design and instructions.
