The TM210 thermal-magnetic release handles overload and short-circuit, with breaking capacities of 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at 690 V. The shunt trip (STL) auxiliary release is built in — order code 3VA9688-0BL30 — so you can remotely trip the breaker from an E-stop or a safety relay without adding an external undervoltage module. Footprint is 130 mm high, 101.6 mm wide, 70 mm deep — a standard 4-pole MCCB envelope that fits most DIN-rail or screw-mount backplates without re-drilling the gland plate. IP40 on the front keeps dust out of the mechanism; the enclosure is rated for indoor panel use, not washdown.","metaTitle":"Siemens 3VA1080-3ED42-0HA0 SENTRON MCCB, 80 A, 4-Pole, 75.6","metaDescription":"Siemens SENTRON 3VA1080-3ED42-0HA0 molded case circuit breaker, 80 A rated, 4-pole, 75.6 kA breaking at 240 V.
