The Siemens 3VA1116-3EF36-0AE0 is a 3-pole SENTRON molded case circuit breaker (MCCB) rated for line protection, carrying a continuous current of 160 A at 40 °C through 50 °C ambient, derating to 150 A at 70 °C. That thermal derating curve means you size the breaker for the actual cabinet temperature, not the nameplate — a panel running at 55 °C loses 2 A, at 65 °C you're down to 153 A. The TM240 thermal-magnetic release handles overload and short-circuit trip coordination without an external trip unit.
Interrupting capacity is rated per IEC 60947-2 at several system voltages: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at both 500 V and 690 V.
Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — a standard 3-pole MCCB footprint that mounts on a DIN rail or panel-mount adapter.
Auxiliary and accessory provisions
The base breaker ships without a trip indicator, undervoltage release, or communication module. No ground-fault monitoring version is included — that's a separate variant if GF protection is needed. The supplied basic switch order code is 3VA11163EF360AA0, which is the factory-fitted internal switch assembly.
