Product details

The Siemens SENTRON 5SM3315-6KK is a 2-pole residual current circuit breaker (RCCB) rated 125 A with 30 mA trip sensitivity, Type A, for 230 V AC 50 Hz systems. It carries a 10 kA short-circuit current rating per IEC 61008-1 and EN 60898, meaning it can safely interrupt fault currents up to that level without upstream cascading — a critical spec for panel coordination.

Snaps onto DIN rail (REG) and occupies 2 modular width units (36 mm wide). Depth is 70 mm — check gland plate clearance before panel layout. Mounts in any position; supply can enter top or bottom. IP20 with distribution board installed and conductors connected.
