It includes thermal overload protection, so it combines earth-fault and overcurrent protection in one DIN-rail module — a space-saving choice for final distribution circuits in residential, commercial, and light industrial panels where you need both ground-fault and overload coverage without a separate MCB. The short-time delayed design means it withstands transient surge currents up to 3 kA without nuisance tripping, making it suitable for circuits with capacitive inrush or switching transients. Rated at 40 A continuous, it handles typical 230 V single-phase submain or feeder circuits up to about 9.2 kW resistive load. Overvoltage category III confirms it is rated for fixed-installation downstream of the utility meter. Conductor range accepts 1 to 16 mm² solid or stranded, covering 1.5 mm² lighting circuits up to 16 mm² feeder tails. Tightening torque of 2.5 to 3 N·m on the screw terminals — standard for this class; a torque screwdriver is recommended during panel build to avoid terminal overheating. Ambient temperature range of -25 to +45 °C and storage range of -40 to +75 °C cover most indoor panel environments. The IP20 rating is typical for DIN-rail devices inside an enclosed distribution board — it is not rated for wet or dusty locations without an outer enclosure. Mounts on DIN rail in any orientation. The test button requires a minimum of 195 V to verify the electronics.","metaTitle":"Siemens 5SM3314-6LA01 SENTRON RCCB, 40 A, 30 mA, Type A, Sho","metaDescription":"Siemens 5SM3314-6LA01 SENTRON RCCB, 2-pole, Type A, short-time delayed, 40 A rated current, 30 mA tripping, 230 V AC, 10 kA SCCR.
