The 3+N-pole configuration and short-time delayed characteristic make it suitable for sub-distribution boards where selective coordination with downstream RCCBs is needed — the delay prevents nuisance tripping from transient leakage currents typical of motor drives or switched-mode supplies. Type A detection covers sinusoidal AC residual currents plus pulsed DC residual currents up to 6 mA — this catches half-wave rectified leakage from single-phase drives, washing machines, or LED drivers that a Type AC RCCB would miss. The 100 mA sensitivity is not for personal shock protection (that requires 30 mA); it is sized for equipment protection and fire prevention on circuits with naturally higher leakage, such as long cable runs or industrial machinery.","metaTitle":"Siemens 5SV3446-6MJ01 RCCB Type A, 63A 100mA 10kA, 3+N-pole","metaDescription":"Siemens 5SV3446-6MJ01 residual current circuit breaker Type A, 63 A, 100 mA, 10 kA, 3+N-pole, 400 V, short-time delayed.
