DPX3 250 HP Circuit Breaker – Reliable Protection for Electrical Installations

The DPX3 250 HP is a three-pole thermal-magnetic circuit breaker designed to protect electrical installations against overloads and short circuits. With a rated continuous current of 50A and an exceptional short-circuit breaking capacity of 100kA at 400V, it ensures reliable and safe operation under demanding conditions. Ideal for professional installers and end-users seeking robust protection.

Functionality and Applications

This circuit breaker is suitable for commercial buildings, industrial facilities, and residential installations with high power demands. Thanks to adjustable overload trip settings (40–50A) and short-circuit trip settings (325–650A), it can be precisely tuned to match the load characteristics. It features two changeover auxiliary contacts, enabling seamless integration with control and signaling systems. The breaker is fixed-mounted and compatible with voltages ranging from 230–690V.
