At 240 V it clears 220 kA — enough for high-fault utility feeds. At 415 V it's 154 kA, at 440 V it's 121 kA, and at 500 V or 690 V it drops to 17 kA. That 17 kA figure at 480/600 V class is the practical limit for most industrial panels; if your upstream transformer can deliver more fault current at those voltages, you need a higher-rated frame upstream or a current-limiting fuse ahead of this breaker. ## Panel fit and thermal management The 3VA1 frame measures 130 mm high, 76.2 mm wide, and 70 mm deep — a compact 3-pole footprint that fits standard distribution panel cutouts.","metaTitle":"Siemens 3VA1180-6EF36-0AA0 SENTRON MCCB, 80 A, 3-Pole, 220 k","metaDescription":"Siemens 3VA1180-6EF36-0AA0 SENTRON molded case circuit breaker, 80 A, 3-pole, TM240 release, 220 kA interrupting at 240 V.
