Circuit breaker DPX3 630 TM 4P 630A 36kA 422009

Power switch for demanding applications

This four-pole power switch DPX3 630 TM from Legrand is a reliable protection for electrical installations with high loads. Designed to operate in networks with a voltage of up to 690V, it provides effective protection against overloads and short circuits, guaranteeing safety and continuity of power supply. The rated continuous current of 630A and the high short-circuit breaking capacity of 36kA make it an ideal solution for industrial and commercial applications.

Design and functionality

The DPX3 630 TM switch is characterized by a solid construction of a fixed device. It has a built-in undervoltage release, which further increases the safety of the installation. The possibility of mounting an optional motor drive expands the functionality of the device, enabling remote control. The main circuit connections located at the front facilitate mounting and connection of wires using screw connections. Additionally, the presence of auxiliary contacts – two normally open and two changeover – allows integration with control and signaling systems. The trip indicator informs about the operation of the protection, facilitating diagnosis of problems in the installation.

Application and benefits

The DPX3 630 TM switch finds wide application in:

• Main distribution boards: as a protective element against overloads and short circuits in the entire circuit.
• Motor power supply: protection of electric motors against damage caused by overload or short circuit.
• Industrial applications: protection of machines and equipment requiring high power consumption.
• Commercial buildings: ensuring safe power supply for large office, commercial or service facilities.

Thanks to the wide range of adjustment of the overload release (504…630A) and short-circuit release (3150…6300A), the switch can be precisely adapted to the specific needs of the installation. Compliance with IEC 60947-1, IEC 60947-2 and IEC 60947-3 standards guarantees high quality and safety of use. The degree of protection IP30 provides protection against accidental contact and against the ingress of solid objects larger than 2.5 mm.
