The type A designation means it detects sinusoidal AC fault currents plus pulsating DC fault currents — the standard choice for circuits with single-phase rectifiers, switched-mode power supplies, or electronic loads that produce pulsed DC leakage. The selective (S-type) characteristic introduces a deliberate time delay so this unit coordinates with downstream RCCBs: in a fault, the closer device trips first, keeping supply to healthy circuits. Packaged as a single unit, 78 x 97 x 85 mm, this is a DIN-rail mounted device sized for distribution boards and sub-distribution panels. The 4-pole format covers three-phase plus neutral, so it protects the entire outgoing circuit. At 125 A it suits main incoming protection or heavy sub-feed duty — think large commercial kitchen equipment, HVAC plant, or industrial machine supply where the full load current sits above 100 A.","metaTitle":"Siemens 5SV3645-8 RCCB, 4-pole Type A Selective, 125A 300mA","metaDescription":"Siemens 5SV3645-8 residual current circuit breaker, 4-pole type A selective, In 125 A, 300 mA, Un AC 400 V.
