Breaking capacity is the headline here: 187 kA at 240 V AC, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V. Those numbers tell you this breaker handles high-fault-current points — main switchboards, transformer secondaries, or large distribution panels where upstream fault current is in the tens of kiloamps. The 690 V rating (17 kA) is useful for 600 V class North American systems or 690 V European industrial grids. Front protection is IP40 — finger-safe from the front but not sealed against dust ingress. Above that, derating kicks in: 76.8 A at 55 °C, 75.2 A at 60 °C, 73.6 A at 65 °C, and 72 A at 70 °C. ## Undervoltage release and auxiliary options There are no auxiliary contacts on this variant (no NO/NC position feedback), and no communication function, no phase failure detection, and no ground fault monitoring. If you need remote status or GFCI, you'd look at a different 3VA1 option with those modules. No trip indicator on the front, so fault type (overload vs short circuit) is not visible without the trip unit diagnostic port.","metaTitle":"Siemens 3VA1180-5EF36-0CA0 SENTRON MCCB, 80 A, 3-Pole, 187 k","metaDescription":"Siemens 3VA1180-5EF36-0CA0 SENTRON molded case circuit breaker, 80 A, 3-pole, line protection with TM240 release.
