Interrupting capacity is the headline here: 187 kA at 240 V AC, 121 kA at 415 V, 75.6 kA at 440 V, and still 17 kA at 690 V. The 4-pole configuration covers three-phase-plus-neutral or dual-supply switching where full isolation is required. Thermal derating is minimal up to 50 °C — still 80 A — then drops to 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, and 74 A at 70 °C. That flat curve through 50 °C means it holds full rating in most ventilated enclosures; only tight, hot cabinets force a derate. Max power loss is 19.2 W, so heat dissipation inside the panel is manageable. ## Panel fit — footprint and mounting The 3VA1180-5GF46-0AA0 measures 70 mm deep, 101.6 mm wide, 130 mm tall. That 101.6 mm width (4 inches) is the standard 4-pole MCCB footprint — it occupies four 25 mm module spaces on a DIN rail or mounts directly to a backplate via the screw terminals.","metaTitle":"Siemens 3VA1180-5GF46-0AA0 SENTRON MCCB, 80 A, 4-Pole, 187 k","metaDescription":"Siemens SENTRON 3VA1180-5GF46-0AA0 molded case circuit breaker, 80 A, 4-pole, TM240 release. 187 kA interrupting at 240 V.
