At 55 °C it's 122 A, at 60 °C it's 120 A, at 65 °C it's 117 A, and at 70 °C it's 114 A. The IP40 front protection means it's suited for indoor distribution boards — not washdown areas. The 4-pole design handles three-phase plus neutral, common for North American and European 4-wire systems. Optional motor drive accessory (listed as available) allows remote tripping or reset.","metaTitle":"Siemens SENTRON 3VA1112-6EF46-0AA0 MCCB, 4P, 125 A, 220 kA a","metaDescription":"Siemens SENTRON 3VA1112-6EF46-0AA0 molded case circuit breaker, 4-pole, 125 A rated current, 220 kA breaking capacity at 240 V.
