Automatic power switch with measurement and communication, 4P 630A HIC463E

Automatic power transfer switch with measurement and communication

The device enables safe and automatic switching between power sources – e.g., public grid and generator – without interruption in voltage monitoring. It operates in I-0-II mode, with the possibility of manual position selection and automatic load‑under‑load switching, eliminating the need for manual intervention in case of power failure.

The built‑in motor drive provides fast and reliable operation, even at high currents. The device features a locking mechanism that allows physical position locking – e.g., with a lock – required during service or maintenance work. All poles are insulated and can be safely disconnected from the circuit, serving as a main disconnect, safety, and maintenance switch.

Each switch position has its own normally closed auxiliary contact that signals the status (e.g., “grid”, “generator”, “off”) to the control system or SCADA. An RJ45 interface enables connection to a communication network – status, current, voltage, or fault data can be transmitted to a monitoring center. This is a key function for installations where power continuity monitoring is mandatory – e.g., hospitals, data centers, or infrastructure facilities.

Cable clamps are designed for large cross‑sections and allow easy connection without the need for additional busbars. The device is mounted directly in the distribution board – it does not require a special enclosure or front mounting. It is permanently fixed and meets the requirements for high short‑circuit capacity systems.

The switch is designed for industrial conditions: it operates at 380–415 V AC, withstands a short‑circuit current of 50 kA and a temporary current of 17 kA. The rated power at 400 V is 414 kW – sufficient for most large three‑phase loads, including motors or heaters.

It is not an emergency stop – it is not intended for immediate circuit disconnection in case of danger. Its purpose is switching between sources, not overload or short‑circuit protection. Therefore it must be used together with appropriate overcurrent circuit breakers.

IP00 protection rating means no protection against touch or foreign objects – thus the device must be installed only in a closed distribution board that ensures personnel safety.
