The 3-pole width of 76.2 mm (3 inches) is the standard MCCB footprint for a 3-pole frame at this rating — it drops into a panel that was laid out for a similar SENTRON 3VA frame without re-drilling the mounting plate.","metaTitle":"Siemens 3VA1180-4EF36-0KH0 SENTRON MCCB, 80 A, 3-Pole, 121 k","metaDescription":"Siemens SENTRON 3VA1180-4EF36-0KH0 molded case circuit breaker, 80 A rated at 40 °C, 3-pole, 121 kA breaking capacity at 240 V.
