It carries an interrupting capacity of 75.6 kA at 240 V, 52.5 kA at 415 V, and 32 kA at 440 V — figures that drop to 11.9 kA at 500 V and 690 V, so the voltage-dependent SCCR profile matters when coordinating with downstream equipment on a 480 V or 600 V distribution bus. In a high-ambient enclosure — say a MCC lineup near a furnace line or in a non-ventilated cabinet — the 55 °C column (78 A) or 60 °C column (77 A) is the real continuous limit, not the nameplate 80 A. Front-face protection is IP40, so the breaker is suited for dry indoor panels but not washdown zones. Dimensions are 130 mm high, 101.6 mm wide, 70 mm deep — a standard 4-pole MCCB footprint that fits most DIN-rail or direct-mount panel layouts without re-drilling. The 70 mm depth leaves clearance behind a 120 mm deep enclosure backplate for wiring and bus connections.","metaTitle":"SENTRON 3VA1180-3EF46-0AA0 MCCB, 80A, 4-Pole, 75.6kA at 240V","metaDescription":"SENTRON 3VA1180-3EF46-0AA0 molded case circuit breaker, 80A rated, 4-pole line protection.
