Automatic power switch with measurement and communication, 4P 2500A HIC494E

Automatic power transfer switch with measurement and communication (AC-23)

The device is designed as a fixed, permanently mounted solution for automatic power switching in distribution installations. It functions as a main, safety and maintenance disconnect — meaning it can safely isolate the circuit during service or fault, while providing full control over the power source. It is not an emergency stop, but its function as a reversal switch allows smooth and safe changeover of the power source between the grid and a generator.

The built‑in motor drive enables automatic switching without manual intervention — ideal for systems where power interruption must be minimal. The device has 4 poles and operates at 380–415 V AC, with a rated continuous current of 2500 A. The making capacity at 400 V is 1645 kW, and the operating power (AC‑23) is 720 kW — meaning it can handle large loads, including motor‑driven equipment.

It is protected against short circuits: it withstands short‑circuit currents up to 78 kA. The main connections are cable‑lugs type — facilitating installation in switchboards without the need for busbars or additional components. There are no auxiliary switching or diverging contacts — only two make contacts that can be used for status signalling or integration with a monitoring system.

There is no optional voltage trigger or motor drive as an add‑on — the motor drive is standardly built‑in. The device is not mounted on a DIN rail or front‑centered — it is installed directly in the switchboard. The IP00 protection class indicates no protection against touch or dust on the front side — therefore it must be mounted in an enclosed panel.

It is intended for systems requiring uninterrupted power and remote communication — e.g., hospitals, data centers or industrial facilities. Its construction allows easy integration with energy‑management systems thanks to the built‑in measurement and communication interfaces (specific protocols are not listed). There are no aesthetic or colour elements — everything is focused on function and reliability.
