The TM240 thermal-magnetic release handles overloads and short-circuits up to the breaker's interrupting rating, which hits 220 kA at 240 V and 154 kA at 415 V. That kind of headroom means it can be placed close to a large transformer or high-fault service entrance without worrying about cascading failure upstream. Past that, the current starts to step down: 76.8 A at 55 °C, 75.2 A at 60 °C, 73.6 A at 65 °C, and 72 A at 70 °C. An undervoltage release (UVR) is built in, and the auxiliary contact configuration comes as 2 auxiliary switches plus a separate trip alarm switch, designated HQ. That gives you two independent status signals and a dedicated alarm contact that changes state only when the breaker trips on a fault, not on manual switching.","metaTitle":"Siemens 3VA1180-6EF36-0CH0 SENTRON MCCB, 80 A, 220 kA at 240","metaDescription":"Siemens 3VA1180-6EF36-0CH0 SENTRON molded case circuit breaker, 80 A rated continuous current, 220 kA breaking capacity at 240 V.
