The Siemens SENTRON 3VA1116-3EF36-0DC0 is a 3-pole molded case circuit breaker rated for 160 A continuous current (Iu) at 40 °C, with a TM240 thermal-magnetic overcurrent release. It carries a breaking capacity of 75.6 kA at 240 V, 52.5 kA at 415 V, and 32 kA at 440 V — figures that define its fault-interruption ceiling for line protection duty.
Above that, it steps down: 153.6 A at 55 °C, 150.4 A at 60 °C, 147.2 A at 65 °C, and 144 A at 70 °C.
Built-in undervoltage release and auxiliary contacts
The auxiliary contact version is two HQ (high-qualified) switches, rated for signaling the breaker state to a PLC or status lamp. The integrated auxiliary trip is order code 3VA9608-0BB25. Latching endurance is 15,000 cycles.
The 76.2 mm width is a standard 3-pole MCCB footprint — it occupies three 25.4 mm modular spaces on a DIN rail or panel-mount base.
