Power circuit breaker with electronic trip unit DPX3 250 EL 3P 160A 25kA 420307

Power circuit breaker with electronic trip unit – reliable installation protection

This three-pole DPX3 250 EL power circuit breaker with a rated current of 160A and a short-circuit breaking capacity of 25kA is a robust solution for protecting electrical circuits. Equipped with an advanced electronic trip unit, it provides precise and fast response to overloads and short circuits, minimizing the risk of damage and downtime. It is a fixed device, designed for mounting on a TH rail, which facilitates installation and servicing.

Functionality and application

This circuit breaker finds application in a wide range of electrical installations – from commercial buildings, through industrial facilities, to more demanding applications. Thanks to the possibility of adjusting the overload trip setting (64…160A) and short-circuit trip setting (96…1600A), it can be perfectly adapted to the characteristics of the protected circuit. The built-in undervoltage release further increases system safety. It has one changeover auxiliary contact and two normally open contacts, allowing integration with control and signaling systems.

Construction and characteristic features

The DPX3 250 EL circuit breaker is distinguished by its solid construction and high quality of workmanship. The connection of the main circuits is made using screw connections, which guarantees a secure and durable connection of the wires. The IP30 degree of protection provides protection against contact and ingress of solid objects. The trip indicator facilitates identification of the device status. The possibility of mounting on a DIN TH rail provides flexibility during installation. Additionally, a motor drive is optionally available for remote control. The ability to isolate the circuit is another important feature that increases safety during maintenance work.
