Maximum power dissipation is 75 W. The 105 mm width, 181 mm height, and 86 mm depth fit standard Siemens 3VA mounting footprints; verify busbar and lug clearance before panel layout.","metaTitle":"Siemens 3VA2110-7MS32-0JA0 SENTRON MCCB, 100A, 330kA at 240V","metaDescription":"Siemens SENTRON 3VA2110-7MS32-0JA0 molded case circuit breaker, 100A rated, 330kA breaking at 240V.
