The selective (S-type) design means it introduces a deliberate time delay on earth faults, allowing downstream RCCBs to clear first — critical for coordination in multi-level distribution boards where you want the faulted subcircuit to isolate without taking the whole board dark. Mounts on DIN rail (REG) in any position, occupies 2 width units (36 mm), and accepts solid or stranded conductors from 1 to 16 mm² at the screw terminals (torque 2.5–3 N·m). IP20 with conductors connected and distribution board installed — standard for enclosed panel use.","metaTitle":"Siemens 5SM3614-8KL SENTRON RCCB, 2-pole Type A Selective, 4","metaDescription":"Siemens 5SM3614-8KL SENTRON RCCB, 2-pole Type A selective, 40 A, 300 mA, 230 V AC, 50 Hz, 10 kA SCCR, DIN rail mount.
