The interrupting curve drops to 52.5 kA at 415 V and 32 kA at 440 V — still substantial for most industrial service entrances and sub-feeders. This is a line-protection device (not a motor-protective breaker), meaning it's sized for cable and busbar protection in switchboards, panelboards, and downstream distribution. ## Thermal derating and power loss At 55 °C it derates to 158 A, at 65 °C to 153 A, and at 70 °C to 150 A. Maximum power loss is 38 W — relevant for enclosure heat calculations when grouping multiple breakers in a sealed panel. ## Mounting dimensions and auxiliary switch configuration Width is 76.2 mm (3 in), depth is 70 mm (2.76 in), height is 130 mm (5.12 in). Comes equipped with 4 auxiliary switches (HQ design) factory-installed. No trip indicator, no undervoltage release, no voltage trigger.","metaTitle":"Siemens 3VA1116-3EF32-0AE0 SENTRON MCCB, 160A, 3-Pole, 75.6k","metaDescription":"Siemens SENTRON 3VA1116-3EF32-0AE0 molded case circuit breaker, 160A thermal rating, 3-pole, 75.6kA interrupting at 240V.
