That 76.2 mm width — three modules on a standard 25 mm DIN-rail pitch — is what determines how many breakers fit in a row. The 70 mm depth matters when the enclosure backplate has limited clearance to the door or a rear bus.","metaTitle":"Siemens SENTRON 3VA1120-6EF32-0HA0 MCCB, 20 A, 3-Pole, 220 k","metaDescription":"Siemens SENTRON 3VA1120-6EF32-0HA0 molded case circuit breaker, 20 A rated continuous current, 3-pole, 220 kA interrupting at 240 V.
