Electrical reference 230V AC 50Hz; Ui 415V Match the project control or supply circuit
Rating / operating window normal 175–255V; overvoltage trip ≥265±10V; undervoltage trip ≤165±10V Use the published range; do not infer missing ratings
Interface for compatible PXB6 breaker accessory interface Verify the compatible breaker, panel, base or rail interface
Wiring 0.5–2.5mm² conductor reference Final conductor and protection selection follows the project design and local 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.
