Type B means it detects AC, pulsating DC, and smooth DC fault currents — needed on drives, UPS feeds, or PV inverters where pure sine-wave RCDs would be blind to DC leakage. The 300 mA threshold and intentional delay make it a selective (S-type) device, so it coordinates with downstream 30 mA RCCBs: a ground fault on a branch trips the branch first, not this main isolator. Snaps onto DIN rail (REG mounting) and occupies 4 width units (72 mm wide). Terminal capacity accepts 1.5 to 25 mm² solid or stranded copper — covers everything from a 2.5 mm² lighting circuit up to a 16 mm² feeder. Tightening torque is 2.5 to 3 N·m, typical for SENTRON screw terminals; no special tooling needed. Supply can land top or bottom; the SIGRES function (residual current detection even when switched off) works with bottom feed.","metaTitle":"Siemens 5SM3626-4 SENTRON RCCB, 63A 300mA Type B, 2-Pole","metaDescription":"Siemens 5SM3626-4 SENTRON RCCB, 2-pole Type B, 63A rated, 300mA trip, short-time delayed, 10kA SCCR.
