The short-time delayed design (0.8 kA surge current withstand per IEC 61008-1) prevents nuisance tripping from transient surge currents like lightning or switching spikes, so it belongs in circuits feeding electronic loads. Supply voltage range is 70–440 V AC at 50/60 Hz, covering standard 230/400 V three-phase panels. The 3 kA surge current resistance and 60 000 A²·s I²t withstand give the integrator confidence against inrush from downstream capacitive loads. Mounts on DIN rail (REG) in any position — no orientation restrictions. Occupies 4 modular width units (72 mm wide, 70 mm deep, 90 mm high) with 60 mm grid spacing. Silicon-free construction suits coating-sensitive environments like automotive paint lines or electronics assembly.","metaTitle":"Siemens 5SV3344-4KK60 SENTRON RCCB, 40 A, 30 mA Type B, 4-po","metaDescription":"Siemens SENTRON 5SV3344-4KK60 RCCB, 40 A rated, 30 mA Type B residual current, 4-pole, short-time delayed, 10 kA SCCR, DIN rail mount.
