The Siemens 3VA1116-4EF32-0DA0 is a 3-pole SENTRON molded case circuit breaker rated 160 A continuous at 40 °C, with a TM240 thermal-magnetic overcurrent release. Its interrupting capacity is 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 500 V and 690 V — that 121 kA figure at 240 V means it can safely clear a bolted fault on a high-capacity 240 V secondary bus without the arc flashing over or the breaker rupturing.
The breaker measures 76.2 mm wide, 130 mm tall, and 70 mm deep — a standard 3-pole MCCB footprint that fits most DIN-rail or panel-mount enclosures without surprises. If you need those, you're looking at a different order code in the 3VA family.
