Dimensions are 70 mm deep, 101.6 mm wide, and 130 mm high — a 4-pole MCCB that fits standard panel-mount cutouts; the IP40 front protection means it's fine for general indoor use but not washdown environments. Maximum power dissipation is 38 W, which should be factored into enclosure thermal calculations, especially when grouping multiple breakers.","metaTitle":"Siemens 3VA1116-4GF46-0AA0 SENTRON MCCB, 160 A, 4-Pole, 121","metaDescription":"Siemens SENTRON 3VA1116-4GF46-0AA0 molded case circuit breaker, 160 A, 4-pole, TM240 release.
