DPX3 250 HP Circuit Breaker – Reliable Protection for Electrical Installations

The DPX3 250 HP is a four-pole (4P) automatic circuit breaker designed to protect electrical circuits with a rated current of 80A. It provides effective protection against overloads and short circuits, ensuring safe operation of the installation. Its robust construction and high breaking capacity (50kA at 400V) make it an ideal solution for demanding industrial installations as well as advanced systems in commercial and residential buildings.

Functionality and Applications

The DPX3 250 HP features a wide rated voltage range (230…690V), enabling universal application across various electrical systems. The adjustable thermal trip setting (63…80A) and magnetic trip setting (400…800A) allow precise tuning to meet the specific requirements of each installation. The absence of built-in earth fault protection enables integration with external RCD devices, ensuring comprehensive safety. Equipped with an off-state indicator, it facilitates rapid identification of the device status and quick localization of potential faults.

Design and Installation

The DPX3 250 HP is a fixed-mounted device designed for installation using bolted connections. Its compact dimensions (140mm width, 165mm height, 112mm depth) allow seamless integration into existing electrical infrastructure. The IP30 protection rating safeguards against accidental contact and ingress of solid objects, enhancing operational safety. Additionally, optional motorized drive mounting extends device functionality by enabling remote control. The breaker is supplied complete with its protective mechanism, simplifying installation and ensuring full readiness for use immediately after removal from packaging.
