DPX3 circuit breaker 250 HP 4P 160 A 100 kA 423175

Compact Circuit Breaker – Reliable Protection for Installations

This four-pole DPX3 250 HP circuit breaker, rated at 160A and with a short-circuit breaking capacity of 100kA, is a robust solution for demanding electrical installations. Designed to protect circuits operating at 230–690V, it provides effective protection against overloads and short circuits. Its fixed-mount construction ensures stability and long-term reliability.

Functionality and Applications

This breaker is ideal for commercial buildings, industrial facilities, and installations requiring high immunity to surge currents. The adjustable thermal trip setting, ranging from 125–160A, allows precise tuning to the specific requirements of the protected circuit. The 100kA short-circuit breaking capacity at 400V ensures rapid and safe response during fault conditions. The built-in trip indicator simplifies device status identification and fault localization.

Design and Installation Features

The DPX3 250 HP breaker features bolted connections for main circuits, ensuring secure and durable wiring. The IP30 protection rating guards against accidental contact and ingress of solid objects. The absence of integrated earth-fault protection and built-in motor drive makes the unit simpler to operate and more versatile. Optional motor drive attachment extends functionality by enabling remote control. The short-circuit trip setting is adjustable from 800–1600A, allowing adaptation to diverse installation operating conditions.
