The 5SV3344-6KK01: The 40 A / 30 mA combination is common for sub-distribution feeding socket outlets or general-purpose circuits where personnel protection is required. Type A detects sinusoidal AC and pulsating DC residual currents — covers most single-phase rectified loads like switching power supplies. The 'super resistant' designation means the device withstands higher surge currents (e.g., from lightning or switching transients) without unwanted tripping, compared to standard RCCBs. The short-time delayed characteristic (200 ms typical) coordinates with instantaneous RCCBs downstream, so a fault on a branch clears before this main device opens. Mounts on 60 mm grid DIN rail, 4 modular width units wide (72 mm), depth 70 mm.
