The TM120M release means the thermal element tracks the load current continuously; the magnetic instantaneous pickup is fixed at the TM120M calibration, which suits motor-starting inrush and feeder protection where you need coordination with downstream devices. This is the starter-protection version of the 3VA platform — the product version field confirms it — so it is configured for motor branch-circuit duty rather than straight distribution. The 50 A rating holds flat from 40 °C through 50 °C, then derates to 49 A at 55 °C, 48 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C. In a warm panel (55 °C ambient) you lose only 1 A; at 70 °C you still have 45 A of headroom. The 70 mm depth clears a standard enclosure with room for wiring and a bus stack behind it. If you need a shunt trip, UVR, or electronic trip unit (ETU), this is the wrong order code — those are separate 3VA variants. The TM120M is a pure thermal-magnetic release; no auxiliary power required, no settings to lose on a power cycle. Lifecycle stage is marked current — this is an active, in-production catalog number. No last-time-buy notice, no phase-out date. ## Thermal performance and power loss Maximum power loss is 14.6 W at rated current.","metaTitle":"Siemens 3VA1150-5MH36-0AA0 SENTRON MCCB, 50 A, 3-Pole, 187 k","metaDescription":"Siemens 3VA1150-5MH36-0AA0 SENTRON molded case circuit breaker, 50 A, 3-pole, TM120M release, 187 kA at 240 V.
