Product Overview
PXB6-MV/MN is a over under voltage release 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.
Over/under-voltage release. normal 175–255V; overvoltage trip ≥265±10V; undervoltage trip ≤165±10V 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 the supply voltage must be monitored against the model's published operating and trip window. Confirm the system voltage, fault/coordination study and whether the project needs over/under-voltage release or another protection function.
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.

|---|---|---|
| Chức năng chính | giải phóng điện áp quá mức/thiểu mức | Confirm the required signal or protection function before ordering |
| Electrical reference | 230V AC 50Hz; Ui 415V | Match the project control or supply circuit |
| Rating / operating window | tần số bình thường là 175–255V; quá áp ≥265±10V; quá áp dưới ≤165±10V | Use the published range; do not infer missing ratings |
| Interface | cho giao diện phụ kiện của máy cắt PXB6 tương thích | Verify the compatible breaker, panel, base or rail interface |
| Wiring | Tham khảo dẫn dây 0,5–2,5 mm² | 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
Over/under-voltage release. Confirm whether the circuit needs status feedback, fault alarm, remote trip or voltage release.
Control-circuit fit
230V AC 50Hz; Ui 415V. Match the control voltage and operating window to the project circuit; never assume a nearby rating is interchangeable.
Mechanical interface
for compatible PXB6 breaker accessory interface. Confirm breaker family, rail/base or panel interface, clearances and maintenance access.
Wiring and documentation
0.5–2.5mm² conductor reference. Request the exact drawing and installation document for the ordered configuration.
Ordering Guide
- Specify the exact model and accessory function: PXB6-MV/MN, over/under-voltage release.
- 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.

PXB6-MV/MN Product FAQ
How does the PXB6-MV/MN work?
The PXB6-MV/MN monitors the supply against its published window: normal 175–255V; overvoltage trip ≥265±10V; undervoltage trip ≤165±10V. When the relevant limit is reached, the compatible breaker accessory function responds as specified by the product design.
What is an over/under-voltage protection device?
It monitors supply voltage and operates when voltage moves outside defined limits. The correct thresholds and reset behavior must be taken from the selected model's documentation.
What voltage range is published for the PXB6-MV/MN?
The published reference is 230V AC 50Hz; Ui 415V and normal 175–255V; overvoltage trip ≥265±10V; undervoltage trip ≤165±10V. Confirm the system voltage, tolerance and installation conditions before ordering.
Is the PXB6-MV/MN the same as a shunt trip release?
No. A voltage release responds to its monitored voltage window, while a shunt trip is controlled by a separate energizing signal. Select the function that matches the protection or control logic.
Which breaker is compatible with the PXB6-MV/MN?
The PXB6-MV/MN is an accessory for a compatible breaker interface. Confirm the exact breaker family, mounting position and coordination requirements.
What should be checked during installation of the PXB6-MV/MN?
Check voltage, thresholds, wiring, breaker interface, enclosure conditions and the manufacturer's installation instructions. Testing must be performed by qualified personnel.
Confirm the Right PXB6-MV/MN Configuration
Share the required function, voltage, interface, quantity, destination market and technical documents. CHAC will review the request against the published accessory data.
