Power switch with thermal-magnetic trip unit DPX3 160 3P 160A 36kA 420087

Power breaker DPX3 – reliable protection for electrical installations

Power breaker DPX3 160A is a three-pole device designed to protect electrical circuits against overloads and short circuits. It is characterized by a high short-circuit breaking capacity, reaching 36kA at 400V, which guarantees safety in the event of a failure. The device's construction, based on thermal-magnetic technology, provides effective and precise protection, and the possibility of mounting on a TH rail facilitates installation and integration with existing systems.

Functionality and application

The DPX3 160A breaker finds application in a wide range of electrical installations – from commercial buildings, through industrial facilities, to installations in residential construction. Its solid construction and high reliability make it an ideal choice for demanding applications. The integrated undervoltage release further increases safety, protecting against the effects of voltage drops in the network. The device is adapted to work in circuits with a rated voltage from 220V to 690V, which ensures its versatility.

Key features and benefits
