It is an instantaneous (short-time delayed: No) design, meaning it trips without intentional delay on a fault — critical for personnel protection where fast disconnection is required. The IP20 protection class applies only when the distribution board is installed with connected conductors; the open unit is not touch-safe without the enclosure. Finger and back-of-hand safe construction meets the basic shock protection requirement during installation. Type A fault current detection covers pulsating DC residual currents (typical from rectifiers, variable-speed drives, or switching power supplies) as well as sinusoidal AC — the standard choice for circuits with electronic loads. The 300 mA trip threshold is a fire-protection level (not personnel protection, which requires 30 mA or lower), suited for submain or feeder circuits where nuisance tripping from leakage is a concern but ground-fault protection is still needed.","metaTitle":"Siemens 5SM3612-6KL SENTRON RCCB, 25 A, 300 mA, Type A","metaDescription":"Siemens 5SM3612-6KL SENTRON 2-pole RCCB, 25 A rated current, 300 mA trip, type A, 10 kA SCCR, 230 V AC.
