The 4-pole configuration covers three-phase plus neutral switching, common in North American and some international distribution schemes where the neutral needs to be disconnected with the phases. Front IP40 protection means it's fine inside a dry enclosure but not washdown-rated. Mounting is standard for the 3VA frame — bolts into a panel or onto a mounting plate, not DIN-rail snap-on. ## Thermal derating and interrupting performance across voltages At 55 °C it drops to 78 A, at 60 °C to 77 A, and at 70 °C to 74 A. That's a gentle slope; you don't lose much headroom unless the ambient is extreme. Interrupting capacity falls off as voltage rises: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V.","metaTitle":"Siemens 3VA1180-5EF46-0AA0 SENTRON MCCB, 4P, 80A, 187kA","metaDescription":"Siemens 3VA1180-5EF46-0AA0 SENTRON 4-pole molded case circuit breaker, 80 A at 40 °C, 187 kA at 240 V.
