No communication function on this variant; it's a straight electromechanical protector. ## Panel fit and physical integration The 105 mm width for a 3-pole 200 A unit is standard for the SENTRON 3VA platform; it'll drop into the same DIN-rail or screw-mount footprint as other 3VA frame-size breakers. That's not trivial in a sealed enclosure — account for the heat when sizing ventilation or calculating internal temperature rise.","metaTitle":"Siemens 3VA1220-5MH32-0DC0 SENTRON MCCB, 200 A, 3-Pole","metaDescription":"Siemens SENTRON 3VA1220-5MH32-0DC0 molded case circuit breaker, 200 A rated, 3-pole, starter protection design with undervoltage release.
