The Siemens 3VA1116-1AA36-0HH0 is a SENTRON switch disconnector built in an MCCB (molded case circuit breaker) form factor. It is rated for 160 A continuous at 40 °C through 50 °C, with a shallow derating curve: 158 A at 55 °C, 155 A at 60 °C, 153 A at 65 °C, and 150 A at 70 °C. It has no overload or short-circuit protection — this is a pure disconnect, not a breaker. The built-in shunt trip release (STL) accepts 12–30 V DC or 24 V AC 50/60 Hz, so you can remote-trip it from an emergency stop circuit or a PLC digital output.
Dimensions are 70 mm deep, 76.2 mm wide, 130 mm tall — the standard 3VA frame size. Front terminal connections accept clamp-type wiring for the main circuit. Mechanical service life is 15 000 operating cycles typical, which covers most switching and isolation duty in distribution boards.
