Power disconnect switch h3+ P630 3x400A HCW400AR

Power disconnector for demanding applications

The h3+ P630 3x400A power disconnector is a robust and reliable device designed for the safe disconnection of electrical circuits. It is suitable for both industrial installations and public buildings where high resistance to loads and frequent switching operations are required. The device's design allows for mounting in distribution boards, facilitating integration with existing infrastructure.

Functionality and application

This three-pole (3P) disconnector with a rated continuous current of 400A is ideal for protecting circuits with a rated voltage of 220…690V. It can function as a main disconnector, emergency stop, and maintenance disconnector – providing versatile use in various scenarios. Thanks to the possibility of using an optional overvoltage release and motor drive, it can be adapted to the specific needs of the installation. The rated operating power for AC-23 at 400V is as high as 407 kW, demonstrating its high efficiency.

Construction and characteristic features

The h3+ P630 disconnector is characterized by a solid construction of a fixed-mounted device. It has cable lugs for connecting conductors, and the locking mechanism provides additional safety during operation. The IP40 degree of protection guarantees protection against contact and ingress of solid objects. The device is adapted for cooperation with busbars (after using an appropriate adapter) and floor mounting. The gray color of the control element facilitates identification in the installation. The short-circuit withstand current Icw is 5 kA, providing effective protection against the effects of short circuits. Additionally, the optional possibility of mounting a motor drive increases user comfort and automates the switching process.
