Circuit breaker DPX3 630 TM 4P 250A 36kA 422005

Power switch – reliable protection for electrical installations

This four-pole DPX3 630 TM switch with a rated current of 250A and a short-circuit breaking capacity of 36kA is a solid solution for securing electrical circuits. Designed for both commercial and industrial applications, it provides effective protection against overloads and short circuits. This switch is particularly useful in installations requiring high reliability and safety.

Characteristics and application

The DPX3 630 TM switch is characterized by a C characteristic, which means it is ideal for protecting circuits powering devices generating inrush currents during start-up, such as motors or transformers. The integrated undervoltage release further increases the safety of the installation, protecting against the effects of voltage drops. The ability to mount additional auxiliary contacts and a motor drive expands the functionality of the switch, adapting it to the specific needs of a given application. Designed to operate in networks with voltages from 220V to 690V, it offers a wide range of applications.

Construction and design features

The switch is made of high-quality materials, which guarantees its durability and reliability. The solid construction of the permanently mounted device ensures stability and resistance to mechanical damage. Screw connection of the main contacts facilitates assembly and ensures a secure electrical connection. The IP30 degree of protection protects against finger contact and the ingress of solid objects larger than 2.5 mm, which is important in industrial environments. An additional trip indicator allows for quick identification of the switch status – informing about its operation in the event of a failure. The rated continuous current at 250A allows for the protection of circuits with high power consumption.
