The 500 mA residual sensitivity (IΔn) is higher than the standard 30 mA personal-protection threshold; this is a fire-protection or equipment-protection device, not a shock-hazard guard. Type A detection covers sinusoidal AC residual currents and pulsating DC residual currents up to 6 mA, covering most electronic loads (VFDs, switching power supplies, UPS rectifiers) that generate pulsed DC leakage. The short-time delayed characteristic means the RCCB will not trip on short-duration leakage spikes up to several hundred milliseconds — a deliberate choice for circuits where nuisance tripping on transient inrush (e.g., capacitor banks, motor starting) must be avoided. ## Deployment context This is a DIN-rail mounted RCCB for installation inside a distribution panel or enclosure. The 4-pole format (3 phases + neutral) suits three-phase systems with a solidly grounded neutral, common in European and Asian industrial and commercial installations. The 500 mA trip level and short-time delay make it appropriate for a submain ahead of multiple branch RCCBs or as a main switch with residual protection in a panel feeding equipment that generates background leakage. The packaging dimensions (78 x 97 x 85 mm) give the panel-builder the footprint for DIN-rail spacing and enclosure fill calculations. A buyer holding an obsolete 4-pole RCCB at a lower amp rating or different sensitivity should verify the panel's existing leakage profile before substituting this higher-current unit.","metaTitle":"Siemens 5SV3745-6KK01 RCCB, 4-pole Type A, 125 A, 500 mA, 40","metaDescription":"Siemens 5SV3745-6KK01 residual current circuit breaker, 4-pole Type A, 125 A rated, 500 mA sensitivity, 400 V AC, short-time delayed.
