The interrupting capacity at 240 V is 187 kA, at 415 V it's 121 kA, at 440 V it's 75.6 kA, and at 690 V it's 17 kA — so this breaker handles high available fault current on the low-voltage side of a distribution transformer without needing a current-limiting fuse upstream. ## Release and auxiliary fit The overcurrent release is a TM240 — a thermal-magnetic type, fixed-trip, no electronic adjustment. That means the thermal pickup and magnetic short-circuit threshold are factory-set; if your load profile needs field-adjustable long-time or short-time pickup, you'd step up to an electronic release in the same 3VA frame. The integrated auxiliary trip order code is 3VA9608-0BB24. Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — a 3-pole MCCB that fits standard SENTRON 3VA mounting feet and busbar systems. Mechanical endurance is 15,000 operations.","metaTitle":"Siemens SENTRON 3VA1180-5EF36-0CH0 MCCB, 80 A, 187 kA at 240","metaDescription":"Siemens SENTRON 3VA1180-5EF36-0CH0 molded case circuit breaker, 3-pole, 80 A rated, 187 kA interrupting at 240 V.
