The TM240 thermal-magnetic trip unit handles overloads and short-circuits without external power. At 240 V it interrupts 121 kA; at 415 V it's 75.6 kA; at 440 V it drops to 25 kA; at 690 V it still holds 11.9 kA. For a 480 V panel feeding motor loads or a transformer secondary, that 25 kA at 440 V covers most industrial service-entrance and feeder applications. That trip alarm gives a discrete signal when the breaker has opened on a fault, which is useful for a PLC input or a panel alarm light. ## What's on the auxiliary contact block The integrated auxiliary trip module carries order code 3VA9688-0BL30. The shunt trip (STL) design lets you trip the breaker remotely by applying a control voltage; no undervoltage release is fitted, so the breaker stays closed on control power loss unless you add that feature separately. ## Temperature derating — what the curve means in a warm cabinet At 55 °C it's 155.6 A; at 60 °C it's 151.2 A; at 65 °C it's 146.8 A; at 70 °C it's 142.4 A. If your panel ambient runs 55 °C and the load draws 150 A, this breaker still holds — no need to oversize.","metaTitle":"Siemens 3VA1216-4EF32-0HH0 MCCB, 160 A, 121 kA at 240 V","metaDescription":"Siemens SENTRON 3VA1216-4EF32-0HH0 molded case circuit breaker, 160 A rated, 3-pole, line protection, 121 kA breaking capacity at 240 V.
