That matters when the breaker shares a DIN-rail enclosure with other heat sources — the 70 mm depth and 76.2 mm width (3-inch footprint) fit standard panel-mount cutouts, but you need to account for the 27.5 W power loss at full load when sizing ventilation.","metaTitle":"Siemens 3VA1110-5EF36-0CC0 SENTRON MCCB, 100 A, 3-Pole, 187","metaDescription":"Siemens SENTRON 3VA1110-5EF36-0CC0 molded case circuit breaker, 100 A, 3-pole, 187 kA interrupting at 240 V.
