The Siemens 3VA1116-6EF32-0AA0 is a 3-pole SENTRON molded case circuit breaker rated for 160 A continuous at 40 °C, with a TM240 thermal-magnetic overcurrent release designed for line protection.
At 55 °C it drops to 158 A, at 60 °C to 155 A, at 65 °C to 153 A, and at 70 °C to 150 A. That's a derating curve you can budget for. The TM240 release means the thermal element is calibrated for a 240 A frame; the magnetic pickup is fixed within that design.
Dimensions are 70 mm deep, 76.2 mm wide, 130 mm high — a standard 3-pole MCCB footprint for DIN-rail or direct-mount panel integration. The 3VA series uses a common mounting pattern across the family, so swapping between current ratings within the same frame size doesn't require re-drilling the subplate.
