The TM240 overcurrent release provides fixed thermal-magnetic protection — thermal for overload, magnetic for short-circuit — with no electronic adjustment. Breaking capacity runs from 121 kA at 240 V through 75.6 kA at 415 V, 52.5 kA at 440 V, down to 11.9 kA at 690 V, which covers most industrial service-entrance and feeder applications. The 80 A continuous rating holds at ambient temperatures up to 50 °C without derating — at 55 °C it's 76.8 A, at 70 °C it's 72 A. IP40 on the front means the breaker face is protected against tools and small solids; the enclosure itself handles the rest. ## Integrated undervoltage release That means the breaker trips automatically if supply voltage drops below a threshold, which is common in safety circuits or motor control centers where you want the breaker open on loss of control power. The integrated auxiliary trip order code is 3VA9608-0BB25. No auxiliary contact version is fitted; if you need status feedback, that's a separate add-on.","metaTitle":"Siemens 3VA1180-4EF36-0DA0 SENTRON MCCB, 80 A, 3-Pole, Line","metaDescription":"Siemens 3VA1180-4EF36-0DA0 SENTRON molded case circuit breaker, 80 A rated current, 3-pole, TM240 release, 121 kA at 240 V.
