The 300 mA residual trip (Type AC) is sized for sinusoidal AC fault currents only — suitable for general-purpose circuits where no pulsed DC or frequency-converter leakage is present. The 40 A rated current and 10 kA SCCR cover most residential and light commercial sub-distribution boards. Conductor cross-section of 1 to 16 mm² solid or stranded accepts standard building wire; the screw terminals need 2.5 to 3 N·m tightening torque. This RCCB is in its current lifecycle stage — still an active catalog number in the SENTRON 5SM3 family. ## Integration notes The N-left variant (product variations field) means the neutral terminal is on the left side — verify orientation against your panel layout before snapping it in. IP20 protection with connected conductors in an installed distribution board. Overvoltage category III, finger- and back-of-hand safe touch protection. Silicon-free construction. The 5SM3 design is a standard residual current circuit-breaker for IEC markets; compliance documentation (RoHS, REACH, relevant IEC standards) is available from the manufacturer.","metaTitle":"Siemens SENTRON 5SM3614-0KL RCCB, 40 A, 300 mA, 2-pole, Type","metaDescription":"Siemens SENTRON 5SM3614-0KL RCCB, 40 A rated, 300 mA trip, 2-pole, Type AC, 10 kA SCCR, DIN rail.
