The 1 kA surge current resistance (IΔm) tells you it can withstand the inrush from a nearby lightning strike or switching transient without welding its contacts shut — important for panels fed from overhead lines or in industrial zones with heavy switching gear. The N-left variant means the neutral terminal is on the left side of the device — check your busbar arrangement for the panel layout. Terminals accept 1 to 16 mm² solid or stranded conductors with a tightening torque of 2.5 to 3 N·m.","metaTitle":"Siemens 5SM3614-6KL SENTRON RCCB, 40A, 300mA, Type A, 2-Pole","metaDescription":"Siemens SENTRON 5SM3614-6KL RCCB, 2-pole Type A, 40 A, 300 mA, 230 V AC, 50 Hz, DIN rail mount, IP20.
