Power circuit breaker with thermal-magnetic trip unit DPX3 160 3P 25A 25kA 420041

DPX3 160 Power Circuit Breaker – Reliable Protection for Electrical Installations

This three-pole DPX3 160 power circuit breaker, with a rated current of 25A and a breaking capacity of 25kA, is a robust solution for protecting electrical circuits. Designed for both professional use and demanding end-users, it provides effective protection against overloads and short circuits. Equipped with a thermal-magnetic trip unit, it offers precise and fast response in emergency situations.

Functionality and Installation

The circuit breaker is designed for mounting on a TH35 rail, making it easy to install in electrical cabinets and enclosures. The ability to connect wires using screw connections (maximum 70mm² stranded or 95mm² solid) ensures a secure and durable connection. The circuit breaker has one normally open and one normally closed auxiliary contact, allowing integration with other automation and control system elements. Additionally, the presence of a trip indicator facilitates identification of the device's status.

Operating Characteristics and Safety

The thermal trip unit is adjustable in the range of 20-25A, allowing you to adapt the sensitivity to the specific needs of the installation. The fixed-setting short-circuit trip unit at 400A provides a fast response to sudden current surges. A breaking capacity of 25kA at 400V guarantees effective protection against the effects of short circuits. The circuit breaker complies with IEC 60947-2 standard, confirming its compliance with the highest safety standards. The built-in undervoltage release further increases the level of installation protection. IP30 protection degree protects against contact with live parts and against the ingress of solid objects larger than 2.5 mm.
