It handles 220 kA interrupting capacity at 240 V and 154 kA at 415 V — numbers that put it squarely in high-fault-duty service for industrial distribution panels where the transformer is big and the cable runs are short. The 800 V rated insulation voltage Ui tells you it's built for 480Y/277 V or 600 V systems without derating the insulation. Panel-mount or DIN-rail adapter, IP40 on the front. The 70 mm depth, 101.6 mm width, and 130 mm height fit standard SENTRON 3VA panel cutouts — if you're replacing a 3VA1 in a running board, the footprint matches the same mounting holes. Use it for feeder protection in switchboards, motor control centers, and distribution panels where you need the interrupting capacity to stay coordinated with downstream breakers.","metaTitle":"Siemens 3VA1180-6EF42-0AA0 SENTRON MCCB, 80 A, 4-pole, TM240","metaDescription":"Siemens SENTRON 3VA1180-6EF42-0AA0 molded case circuit breaker, 80 A rated, 4-pole, 220 kA at 240 V, TM240 release.
