Instantaneous tripping, no short-time delay. The 10 kA short-circuit current rating (SCCR) matches the withstand of typical distribution board busbars in IEC 61008-1 installations. Mounts in any orientation. IP20 with conductors connected and distribution board installed. Silicon-free construction. Overvoltage category III. The 300 mA sensitivity suits circuits where 30 mA nuisance tripping is a concern — typically subdistributions feeding fixed equipment, not socket outlets. The type A detection covers pulsating DC residual currents from rectifier loads. ## Panel fit notes Four-pole unit occupies 72 mm on the DIN rail. Depth 70 mm matches standard distribution board enclosure depths; no overhang on a 60 mm grid. Supply feed top or bottom. Ambient range -25 °C to 45 °C; storage down to -40 °C.","metaTitle":"Siemens 5SV3644-6 SENTRON RCCB, 4P 40A 300mA Type A","metaDescription":"Siemens SENTRON 5SV3644-6 RCCB, 4-pole, 40 A, 300 mA, type A, 400 V AC, 10 kA SCCR, active production.
