The Siemens SENTRON 3VA2116-5KP32-0HC0 is a 3-pole molded case circuit breaker rated for 160 A continuous current across the full 40 °C to 70 °C ambient range — no derating needed up to 70 °C, which is unusual for this class and saves headroom in a warm enclosure. Breaking capacity hits 187 kA at 240 V, 121 kA at 415 V and 440 V, then drops to 75.6 kA at 500 V and 3.7 kA at 690 V. This is a line-protection design with a built-in communication function, so it can talk to a BMS or PLC for load shedding and trip-event logging. The auxiliary switch pack is two HQ switches, and the shunt trip (STL) release lets you remote-trip it from a safety circuit or emergency stop chain.
The 3VA1110-5ED36-0AC0, 3VA1112-5EE32-0AA0, and 3VA1110-5EF32-0AM0 are smaller-frame SENTRON MCCBs with lower interrupting ratings. The 3VA2116-5KP32-0HC0 steps up to a 160 A frame and 187 kA IC at 240 V.
