The integrated shunt trip (STL) release lets a remote signal or safety circuit trip the breaker independently of overload or short-circuit conditions, which is typical for emergency-off or interlock schemes. The TM210 thermal-magnetic release provides inverse-time overload protection and instantaneous short-circuit response — standard for motor branch circuits and general distribution where no electronic adjustment is needed. The 76.2 mm (3 in) width is the standard footprint for a 3-pole SENTRON 3VA frame at this rating — it occupies three 25 mm module positions on a DIN rail or mounts directly on a backplate with the supplied screws. ## Breaking Capacity by Voltage — Selectivity Planning The interrupting ratings span the voltage range a panel builder actually encounters: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at both 500 V and 690 V (–). For a 400 V distribution board with 50 kA available fault current, this breaker's 52.5 kA at 415 V gives a slim margin — coordination upstream with a current-limiting fuse or a higher-rated SENTRON 3VA frame is worth modeling if the transformer size pushes fault levels above 50 kA. At 240 V the 75.6 kA covers virtually all North American panelboard applications. ## Temperature Derating Curve At 55 °C it derates to 78 A, at 60 °C to 77 A, and at 65 °C to 75 A (–). At 70 °C it still carries 74 A. If the breaker sits next to a heat source or in an unventilated enclosure, the 65 °C derating point is the one to design around — losing only 5 A from the nominal rating means the thermal design is forgiving.","metaTitle":"Siemens 3VA1080-3ED36-0JA0 SENTRON MCCB, 80 A, 3-Pole, Shunt","metaDescription":"Siemens SENTRON 3VA1080-3ED36-0JA0 molded case circuit breaker, 80 A at 40 °C, 3-pole, 75.6 kA at 240 V, shunt trip release.
