Switch disconnector for isolation and switching duty
The Siemens 3VA1116-1AA42-0BH0 is a 4-pole switch disconnector from the SENTRON 3VA1 family, rated for 160 A continuous current (Iu) with a 70 mm depth, 101.6 mm width, and 130 mm height. It is designed for isolation and safe disconnection under load in industrial panels, not for overload or short-circuit protection — it carries no overcurrent release. The busbar connection on the front terminal suits it for fixed distribution boards where a dedicated disconnect point is needed ahead of downstream protection.
Undervoltage release and auxiliary contacts onboard
The auxiliary contacts are wired separately from the main circuit, so they can be used for remote status without interfering with the power path.
Rated for 690 V AC and 600 V DC isolation
IP40 on the front keeps tools out.
