Automatic power switch 4P 3200A HIC495G

Automatic power switch 4P 3200A – solution for critical circuits

This device functions as a main, safety and maintenance disconnect – it is not an emergency stop, but provides safe circuit disconnection under normal operating conditions. It has an integrated motor drive, allowing automatic switching between power sources without manual intervention. The locking mechanism prevents accidental closing during service – a key feature for installers working in high‑risk zones.

Capable of carrying 3200 A continuous current at 380–415 V, it handles loads up to 720 kW (AC-23) and can safely switch power up to 2106 kW at 400 V. It withstands short‑circuit currents of 78 kA – a value significantly higher than some online sources (50 kA), confirming its suitability for installations with high fault‑current levels.

It has 4 poles and cable connections via terminals – no need for mounting on a busbar or in 4‑hole panels. The unit is permanently mounted, intended for installation in distribution boards. An IP00 rating on the front indicates that live parts are not protected – installation must be performed in a suitably designed enclosure.

Available are 2 auxiliary normally‑closed contacts, which can be used for position indication (e.g., “source A active”) or for controlling automation circuits. The absence of make‑and‑break or switching contacts limits functions, but this is intentional – the device focuses on the primary task: safe and reliable switching.

There is no voltage‑trigger or external drive option – everything is integrated. It is not a plug‑in or front‑mount component. Its construction is simple yet robust: intended for professionals who need a solid, reliable solution without unnecessary features.
