DPX3 circuit breaker 250 HP 4P 25 A 70 kA 423137

Reliable Protection for Electrical Installations – DPX3 250 HP Circuit Breaker

The DPX3 250 HP circuit breaker is a four-pole device designed for effective protection of electrical circuits with a rated current of 25A. Its application in systems with voltage ranging from 230–690 V ensures versatility and suitability for diverse applications—from commercial buildings to industrial facilities. Its high short-circuit breaking capacity (70 kA at 400 V) guarantees safety and minimizes the risk of damage during fault conditions.

Construction and Application

This breaker features a robust, fixed-mount design. The bolted connection of main contacts ensures secure and reliable connections, while the absence of requirement for TH or DIN rail mounting simplifies installation in specialized environments. An explicit off-position indicator enables rapid identification of the device’s status and quick diagnosis of potential issues. The option to integrate a motorized drive extends functionality, enabling remote control.
