It holds the interrupting rating at 121 kA at 240 V, 75.6 kA at 415 V, and 52.5 kA at 440 V — figures that matter for fault-current coordination downstream of a transformer or generator bus. At 55 °C it derates to 76.8 A, at 60 °C to 75.2 A, at 65 °C to 73.6 A, and at 70 °C to 72 A. At 240 V the breaker clears 121 kA; at 415 V it clears 75.6 kA; at 440 V it clears 52.5 kA; at 690 V it clears 11.9 kA. The interrupting rating drops as system voltage rises — this is typical for an MCCB with a fixed arc chamber. For a 480 V distribution panel the relevant figure is the 440 V rating (52.5 kA) since the next standard test voltage is 480 V; the 690 V rating (11.9 kA) applies only if the system neutral is solidly grounded and the line-to-line voltage is above 480 V. ## Release and accessories The TM210 release is a thermal-magnetic type — thermal for overload, magnetic for short-circuit. A shunt trip (STL) is present as the auxiliary release design; the integrated auxiliary trip is order code 3VA9688-0BL30. The trip indicator is not present, so a remote indication of trip state requires an external auxiliary contact block to be added. ## Physical integration and environment","metaTitle":"Siemens 3VA1080-4ED36-0HA0 SENTRON MCCB, 80 A, 3-Pole, TM210","metaDescription":"Siemens SENTRON 3VA1080-4ED36-0HA0 molded case circuit breaker, 80 A rated, 3-pole, TM210 release, 121 kA at 240 V.
