Breaking capacity is the headline spec here: 187 kA at 240 V AC, 121 kA at 415 V, 75.6 kA at 440 V, and still 7.5 kA at 690 V. The 7.5 kA at 690 V is still respectable for a 3-pole breaker on 690 V line-to-line systems (common in mining or marine). ## Panel fit and thermal management The 3VA1180-5MH36-0AA0 measures 130 mm high, 76.2 mm wide, and 70 mm deep — a 3-pole MCCB footprint that fits standard Siemens 3VA panel mounting. Maximum power loss is 19.2 W — that heat has to be dissipated inside the enclosure, so factor it into your thermal budget if you're stacking multiple breakers in a sealed cabinet. The 80 A rating holds flat from 40 °C to 50 °C, then derates gradually to 74 A at 70 °C. ## What the TM120M release means for your motor circuit The TM120M designation tells you the thermal-magnetic release has a fixed thermal pickup of 80 A (the '120' refers to the frame size, not the amp setting) and a magnetic trip that's adjustable or fixed depending on the variant — on this order code it's a factory-set unit. For starter protection, the TM120M provides the coordinated overload and short-circuit protection that a motor starter needs, without relying on an external relay. The 3VA1180-5MH36-0AA0 has no undervoltage release, no voltage trigger, no trip indicator, and no communication function — it's a straight electromechanical breaker with no auxiliary electronics.","metaTitle":"Siemens 3VA1180-5MH36-0AA0 SENTRON MCCB, 80 A, 3-Pole, TM120","metaDescription":"Siemens 3VA1180-5MH36-0AA0 SENTRON molded case circuit breaker, 80 A rated at 40 °C, 3-pole, TM120M thermal-magnetic release, 187 kA at 240 V.

The main difference is the rating and release — the 3VA1180-5MH36-0AA0 is an 80 A starter-protection breaker with a TM120M release, while the 3VA1010-2ED32-0JA0 is a different amp rating and release type.
