At 415 V the rating drops to 121 kA, at 440 V to 75.6 kA, and at 500/690 V to 17 kA, so the voltage you're protecting against determines the fault level this breaker can handle. No communication function is built in, so if you need remote trip or energy monitoring, you'll add an external module. ## Thermal derating and power loss Above that it derates: 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, and 74 A at 70 °C. Maximum power loss is 21.7 W, which is modest for an 80 A frame; it won't cook adjacent components in a well-ventilated enclosure. The 70 mm depth means it clears most shallow enclosures — check your gland-plate clearance if you're retrofitting into a tight cabinet.","metaTitle":"Siemens 3VA1180-5EF32-0DH0 SENTRON MCCB, 80 A, 3-Pole, 187 k","metaDescription":"Siemens SENTRON 3VA1180-5EF32-0DH0 molded case circuit breaker, 80 A, 3-pole, 187 kA breaking capacity at 240 VAC.
