Its Type B characteristic detects smooth DC residual currents and mixed-frequency AC/DC faults — the kind generated by variable-frequency drives, UPS systems, and power supplies that a standard Type A cannot see. The short-time delayed design (SIGRES function) prevents nuisance tripping from transient surge currents or inrush from connected electronics, making it a fit for mixed-load sub-distribution boards where both sinusoidal and pulsed DC leakage are present. Rated short-circuit capacity sits at 10 kA per IEC 61008-1, with a maximum permissible series fuse of 100 A upstream for fault backup. ## Integration into the sub-distribution board Snap-on DIN rail (REG) mounting, 72 mm wide (4 MW), 70 mm installation depth. Supply can enter from top or bottom; for the SIGRES function the supply remains live at the top terminal even when the device is switched off. IP20 rating applies only when the distribution board is installed with connected conductors — treat it as a panel-internal device, not for exposed mounting. Silicon-free construction suits environments where outgassing could affect contacts or electronics. Operating frequency is 50/60 Hz; supply voltage for the test circuit is 70–250 V AC.","metaTitle":"Siemens SENTRON 5SV3624-4 RCCB, Type B, 40 A, 300 mA","metaDescription":"Siemens SENTRON 5SV3624-4 RCCB, 2-pole, Type B, short-time delayed, 40 A, 300 mA, 230 V AC.
