The interrupting ratings are substantial: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 690 V, meaning it can clear high-fault currents on 480 V or 600 V class distribution without cascading upstream breakers. Above that, derating begins: 76.8 A at 55 °C, 75.2 A at 60 °C, 73.6 A at 65 °C, and 72 A at 70 °C. In a sealed, uncooled enclosure running at 60 °C, plan for 75 A continuous load maximum. Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — a standard 3-pole MCCB footprint for DIN-rail or screw-mount panel integration. The depth of 70 mm means it fits shallow enclosures where 100 mm+ breakers would conflict with gland plates or rear wiring ducts. ## Auxiliary Trip and Accessory Integration The integrated auxiliary trip module carries order code 3VA9688-0BL30 — this is the shunt trip coil assembly factory-fitted to this variant. The MCCB also includes a voltage trip trigger function, allowing remote opening via an external signal. Rated insulation voltage (Ui) is 800 V, confirming suitability for 480/277 V and 600/347 V distribution systems. For DC network applications, Siemens directs to the 3VA molded case circuit breaker device manual for switching power values.","metaTitle":"Siemens 3VA1180-4EF36-0HH0 SENTRON MCCB, 80 A, 121 kA at 240","metaDescription":"Siemens 3VA1180-4EF36-0HH0 SENTRON molded case circuit breaker, 80 A rated, 121 kA interrupting at 240 V. 3-pole, TM240 release, shunt trip.
