Automatic power switch with measurement and communication, 4P 1000A HIC490E

Automatic power transfer switch with motorized drive and measurement

The device functions as a full‑featured main, safety and maintenance disconnect — no additional components required. It features an integrated motorized drive that automatically transfers load between power sources without manual intervention. Operates in 4‑pole systems with a rated voltage of 380–415 V AC, and its rated current of 1000 A allows it to serve circuits up to 658 kW at 400 V.

Short‑circuit capacity of 100 kA ensures safety even in extreme fault conditions — it remains undamaged when protected by gG fuses. The I_cw value (64 kA) confirms resistance to brief fault currents, which is critical in installations with large motors or transformers.

Construction and installation

Designed for mounting in distribution boards — no special frames or enclosures are needed. Fixed mounting and cable clamps enable direct wire connection without the need for DIN rails. Not suitable for front‑mount or 4‑hole panel installation — the design is dedicated exclusively to cabinet mounting.

It has one normally‑closed auxiliary contact — sufficient for position signalling (e.g., “source A active”) or integration with a SCADA system. The absence of make‑and‑break contacts provides simplicity and minimalism — no unnecessary components that could cause errors.

Functionality and communication

The device not only switches but also monitors network status. Built‑in measurements and communication (protocol not specified) allow remote tracking of voltage, current and switch status. This is not a standard ATS — it is an intelligent infrastructure element that can be part of an energy‑management system.

Mechanical locking prevents accidental closing during service — the installer can be sure the device stays in the manually selected position. It does not act as an emergency stop — there is no “STOP” button, but it serves as a safe isolation point.

All of this is housed in a solidly built IP00 enclosure — requiring protection from dust and moisture by an appropriate cabinet enclosure. It has no NEMA rating or controller colour scheme — this is a technical device, not an aesthetic one.
