Circuit breaker DPX3 630 TM 3P 400A 36kA 422002

Power breaker DPX3 630 TM – reliable protection for electrical installations

The DPX3 630 TM breaker is a three-pole power breaker with a rated current of 400A and a short-circuit breaking capacity of 36kA. Designed by Legrand, it is a key element of protection in electrical installations, both for professionals and end-users. This device combines a compact design with high performance, providing effective protection against overloads and short circuits.

Construction and application

The DPX3 630 TM breaker is designed for mounting in electrical distribution boards and is used to protect circuits with high loads. Its solid construction and the use of high-quality materials guarantee long-lasting and trouble-free operation. The built-in undervoltage release further increases the safety of the installation, protecting against the effects of voltage drops. The possibility of mounting an optional motor drive expands the functionality of the device, enabling remote control.

This breaker finds wide application in commercial buildings, industrial plants, and residential installations with high power demand. Thanks to the wide range of overload (320-400A) and short-circuit (2000-4000A) release settings, it can be precisely adapted to the specific requirements of a given installation. It provides not only protection against damage but also increases the reliability of the entire electrical system.

Key features and benefits

• High short-circuit breaking capacity (36kA): effectively interrupts the circuit in the event of a short circuit, minimizing the risk of damage and fire.
• Wide range of release settings: allows precise adjustment to the load characteristics and ensures selective protection of the installation.
• Built-in undervoltage release: protects against the effects of voltage drops, which can damage connected devices.
• Possibility of mounting a motor drive: provides remote control of the breaker, which increases comfort and enables integration with building automation systems.
• Solid construction: guarantees long-lasting and trouble-free operation in difficult operating conditions.
• Availability of auxiliary contacts: allows signaling of the breaker status and integration with control systems. Two normally closed and two normally open auxiliary contacts are available.
• Compliance with IEC/EN 60947-2 standards: ensures the safety and reliability of the device in accordance with applicable standards.
• IP30 protection degree: protects against access to hazardous live parts and against the ingress of solid objects larger than 2.5 mm.
• Screw connection type: ensures a secure and durable connection of wires to the breaker.

Thanks to these features, the DPX3 630 TM breaker is an optimal solution for demanding electrical installations, providing safety, reliability, and comfort for both installers and end-users.
