It is an instantaneous type AC device — designed to detect sinusoidal AC fault currents only, not pulsating DC or smooth DC. The N-left terminal orientation means the neutral conductor connects on the left side of the unit, which matters when laying out the DIN-rail assembly in a distribution board. The 63 A rated current sets the continuous load capacity — this RCCB carries up to 63 A without tripping thermally. The 100 mA residual trip is a higher threshold than the common 30 mA for personal shock protection; 100 mA units are typically specified for equipment protection or where nuisance tripping from leakage in long cable runs or industrial loads would be a problem. The conductor cross-section range of 1.5 to 25 mm² solid or stranded covers most panel wiring from control circuits up to main feeder tails. The 70 mm installation depth and 2.5 width units mean it occupies 2.5 modular spaces (about 45 mm) on a DIN rail — a standard footprint for a 2-pole RCCB in European distribution boards. ## Deployment context This RCCB snaps onto a DIN rail (REG) in any mounting position, with the supply feed acceptable from top or bottom.","metaTitle":"Siemens SENTRON 5SM3416-0KL RCCB, 2-pole, 63 A, 100 mA, 230","metaDescription":"Siemens SENTRON 5SM3416-0KL residual current circuit breaker, 2-pole, type AC, 63 A rated current, 100 mA trip, 230 V AC.
