At 240 V it interrupts 121 kA; at 415 V, 75.6 kA; at 440 V, 52.5 kA; and at 500 V or 690 V it still clears 11.9 kA. This variant includes an integrated shunt trip (STL) release — the auxiliary release type listed as design of the auxiliary release. That means a remote signal (from a safety relay, E-stop circuit, or PLC digital output) can electrically trip the breaker without a handle operator. ## Thermal derating — the real continuous current At 55 °C it derates to 158 A, at 60 °C to 155 A, at 65 °C to 153 A, and at 70 °C to 150 A. The 76.2 mm width (3 inches) is the critical dimension for multi-breaker spacing in a panel layout; three of these side-by-side occupy 228.6 mm plus the required air gap between units. No trip indicator on the front face, so fault status is read from the handle position or via the shunt trip circuit.","metaTitle":"Siemens 3VA1116-4EF32-0HA0 SENTRON MCCB, 160 A, 3-Pole, Shun","metaDescription":"Siemens SENTRON 3VA1116-4EF32-0HA0 molded case circuit breaker, 160 A at 40 °C, 3-pole, TM240 release, 121 kA at 240 V.
