Automatic power switch with measurement and communication, 4P 2000A HIC493E

Automatic power transfer switch with measurement and communication

This device functions as an automatic transfer switch (ATS) that, in the event of a power outage – e.g., from the main grid – automatically transfers the load to a backup source without manual intervention. It is designed for continuous operation in systems where loss of power has critical consequences – such as hospitals, data centers, industrial installations, or infrastructure facilities.

It has 4 poles and is intended for mounting in distribution panels. Its rated continuous current is 2000 A, and the operating voltage range is 380–415 V AC. The 1316 kW rating is the maximum power it can safely make and break at 400 V, meaning it can handle large loads such as motors or industrial heaters.

The built‑in motor drive enables fast and precise switching without the need for additional mechanisms. The device features a locking mechanism that physically secures the position, preventing accidental switching during service or fault conditions – a key safety feature for personnel.

It also serves as a main disconnect, safety, and maintenance switch, fulfilling all functions required by standards for distribution points. It is not an emergency breaker (it lacks overload‑trip capability) but acts as an isolation point, allowing safe access to the installation during maintenance.

The unit includes 2 normally closed auxiliary contacts that can be used for status signalling (e.g., “grid power” / “generator power”) or integration with BMS/SCADA systems. The absence of make‑and‑break contacts means there is no additional control function – the focus is solely on the primary switching operation.

The front‑panel protection rating is IP00, so it offers no protection against dust or water. This is typical for devices installed in closed panels where the panel enclosure provides the necessary protection. There is no option for front‑ or intermediate mounting – the device is fixed directly to the panel frame.

Compliant with low‑voltage installation standards. It can be used in systems requiring energy measurement and communication – although the technical data do not specify a protocol (Modbus, CAN, etc.), the “measurement and communication” designation suggests possible integration with monitoring systems.

There is no option for an external drive or voltage trigger – everything is integrated and ready‑to‑use “out‑of‑the‑box”. No additional modules are required for basic operation.
