The Siemens SENTRON 3VA1116-6EF32-0HH0 is a 3-pole molded case circuit breaker rated for line protection, carrying a continuous current Iu of 160 A and an insulation voltage Ui of 800 V. Its interrupting capacity hits 220 kA at 240 V, 154 kA at 415 V, and 75.6 kA at 440 V — numbers that matter when coordinating downstream faults on a high-fault panel feed.
Thermal-magnetic curve and temperature derating
The overcurrent release is a TM240 — thermal-magnetic, fixed, 240 A frame, set at the factory to the 160 A rating. The breaker holds 160 A flat from 40 °C through 50 °C, then derates to 153.6 A at 55 °C, 150.4 A at 60 °C, 147.2 A at 65 °C, and 144 A at 70 °C. If your panel ambient runs above 50 °C, the real-world continuous current is lower than the nameplate Iu.
Auxiliaries and trip options
Factory-fitted with 2 auxiliary switches plus 1 trip alarm switch (HQ type), and a shunt trip release (STL) for remote tripping. No undervoltage release, no ground-fault monitoring, no phase-failure detection, no communication module — this is a pure line-protection breaker, not a power-monitoring device. The integrated auxiliary trip order code is 3VA9688-0BL30 if you need a spare or replacement.
Mounting and environment
Dimensions: 130 mm high, 76.2 mm wide, 70 mm deep. Front protection IP40 — suitable for enclosed panel mounting where no water jets or dust ingress are expected. Operating temperature range -25 °C to 70 °C; storage from -40 °C to 80 °C. Mechanical endurance rated at 15 000 cycles.
