Power switch with thermal-magnetic trip unit DPX3 160 3P 63A 25KA 420043

DPX3 Power Circuit Breaker – Reliable Protection for Your Installation

This three-pole DPX3 power circuit breaker with a rated current of 63A and a short-circuit breaking capacity of 25kA is a solid solution for protecting electrical installations. Designed by Legrand, it combines high performance with compact dimensions, making it easy to install even in limited spaces. Equipped with a thermal-magnetic trip unit, it provides comprehensive protection against overloads and short circuits, minimizing the risk of damage and fire.

Functionality and Application

The DPX3 circuit breaker finds application in a wide range of electrical installations – from home distribution boards to industrial facilities. It is perfect for protecting circuits with high power demand, such as heat pumps, electric heating or industrial equipment. The possibility of mounting on a TH rail allows for quick and easy integration with existing infrastructure. Additionally, the presence of a trip indicator facilitates troubleshooting and quick identification of the causes of failures.

Construction Features and Benefits

• Thermal-magnetic trip unit: Provides effective protection against overloads and short circuits, adapting the characteristics to the specifics of the load (setting range 50.4…63A).
• Short-circuit breaking capacity 25kA: Guarantees safe disconnection of the circuit in the event of a short circuit, protecting devices and the installation from serious damage.
• Three-pole design (3P): Provides full protection for three-phase electrical circuits.
• Possibility of mounting on TH rail: Enables easy and quick installation in standard distribution boards.
• Screw connection type: Ensures secure and durable connection of wires.
• Trip indicator: Facilitates identification of the circuit breaker status and causes of failure.
• Optional motor drive: Allows for remote control of the circuit breaker (option).
• Integrated undervoltage release: Additional layer of protection for sensitive devices.
• Protection degree IP30: Protection against touching with fingers and against solid objects larger than 2.5 mm – suitable for most indoor applications.

Thanks to this, the circuit breaker not only protects the installation, but also increases its reliability and safety of use for both professionals performing installations and end-users using electrical energy every day.
