That matters when you're stuffing this into a crowded panel where ambient climbs; you don't lose headroom until the enclosure hits 55 °C. The TM210 thermal-magnetic release handles the overload and short-circuit protection curve. Three poles, line protection version — no communication function, no phase failure detection, no ground fault monitoring. This is a straight-ahead feeder or branch breaker, not a multifunction power monitor. ## Interrupting capacity that covers most industrial service entrances Interrupting ratings: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, 11.9 kA at 690 V. At typical 480Y/277 V distribution, you're looking at a value between the 415 V and 440 V numbers — well above what most panelboards upstream can deliver. The 690 V figure is lower, so verify coordination if this lands on a 600 V class system. ## Active lifecycle — no end-of-life scramble The integrated auxiliary trip is order code 3VA9608-0BB24 — that's the undervoltage release (UVR) module that ships with this breaker. If you're replacing a unit or stocking spares, make sure that UVR coil matches your control voltage; the base breaker doesn't carry an undervoltage release without that add-on module. Depth of 70 mm leaves room for wiring gutters behind the breaker in a typical 200 mm deep enclosure. No auxiliary contacts onboard, no trip indicator, no voltage trigger. If you need remote status feedback, plan for an external auxiliary contact block or a separate monitoring relay.","metaTitle":"Siemens 3VA1080-4ED32-0CA0 SENTRON MCCB, 80 A, 3-Pole, TM210","metaDescription":"Siemens SENTRON 3VA1080-4ED32-0CA0 molded case circuit breaker, 80 A, 3-pole, TM210 thermal-magnetic release, 121 kA at 240 V.
