The top or bottom supply feed gives flexibility in panel layout. IP20 rating applies once the distribution board is installed with conductors connected — standard for enclosed panel gear. The short-time delay feature (switching function short-term delayed) prevents nuisance tripping from transient leakage currents, which is useful on circuits with motor drives or switching power supplies that generate brief inrush leakage. The 230/400 V AC supply voltage at 50/60 Hz covers standard European and many international panel voltages. Silicon-free construction is noted for environments sensitive to silicone outgassing.","metaTitle":"Siemens 5SV4444-0LA01 SENTRON RCCB, 4-pole, 40 A, 100 mA, Ty","metaDescription":"Siemens SENTRON 5SV4444-0LA01 residual current circuit breaker, 4-pole, Type AC, 40 A, 100 mA, short-time delayed, 10 kA SCCR.
