Type A detection means it catches both sinusoidal AC residual currents and pulsating DC fault currents — the standard for modern electronics-heavy loads like VFDs, switching power supplies, and LED drivers. Instantaneous trip (no short-time delay) makes it suitable for direct shock protection, not just equipment protection. Wire range accepts 1 to 16 mm² solid or stranded, covering most panel wiring from control circuits up to feeder-size conductors. The 70 mm depth and 36 mm width (2 width units on DIN rail) fit standard distribution boards; mounting position is unrestricted. Snaps onto DIN rail (REG profile). IP20 with the distribution board installed and conductors connected — that's a panel-enclosed rating, not standalone. Silicon-free construction, so it's safe for use in environments where silicone outgassing could contaminate sensitive contacts or optics.","metaTitle":"Siemens 5SM3612-6 SENTRON RCCB, 2-pole 25A Type A, 10kA","metaDescription":"Siemens 5SM3612-6 SENTRON 2-pole RCCB, 25A rated, Type A, 10kA SCCR, 230V AC.
