ACDC 40A 4P Three‑Position Changeover

Three positions (I-0-II) — allows selecting between two supply sources or off (isolation)

4-pole switching — switches four conductors simultaneously (e.g. 3 phases + neutral, or in DC arrays)

Rated current: 40 A — suitable for moderate load switching

Modular / DIN-rail compatible designs — many versions mount easily in electrical panels

Robust mechanical construction — designed for multiple switching operations

Clear position indication — handles with visible position (left, centre off, right)

Safe isolation — “OFF” centre position fully isolates the circuit

Compatible with both AC & DC systems (check product spec)

Accessory support — some models accept auxiliary contacts or locking mechanisms

IP / protection options — in some models, IP ratings or enclosed housings for outdoor / harsh environments
