Moulded case circuit breaker with thermal-magnetic trip unit DPX3 250 3P 100A 50kA 420265

Robust protection of electrical installations with DPX3 250 circuit breaker

DPX3 250 circuit breaker is a reliable element protecting electrical installations against overloads and short circuits. The three-pole design, combined with a thermal-magnetic trip unit, guarantees effective protection in both commercial and industrial installations. The rated continuous current of 100A and high short-circuit breaking capacity (50kA at 400V) make it an ideal solution for circuits with high power demand.

Functionality and installation

The DPX3 250 circuit breaker has been designed for easy installation and convenient operation. The possibility of mounting on a TH rail allows for quick integration with the existing infrastructure. The location of the main circuit connections on the front side facilitates the connection of wires, and the screw connection ensures a secure and durable connection. Additionally, the trip indicator allows for quick identification of the device status.

• Versatility: Can be used in installations with a rated voltage from 220 to 690V.
• Flexibility: Complete with protection, and optional possibility of mounting on a DIN TH rail and motor drive.
• Safety: Equipped with a built-in undervoltage release, which further increases safety.
• Configuration: Adjustable overload (80-100A) and short-circuit (500-1000A) trip setting range allows for precise adjustment to the specifics of the protected installation.
• Signaling: Has a switched and normally open auxiliary contact, which allows integration with monitoring and control systems.
• Protection class: IP30 class provides basic protection against contact and ingress of solid objects.

The DPX3 250 circuit breaker is not only a protective element, but also an investment in the long-term and trouble-free operation of the electrical installation. Its solid construction and high quality workmanship guarantee reliability even in difficult working conditions.
