Rated current is 125 A; residual tripping current is 300 mA. Short-circuit breaking capacity is 10 kA at 230 V AC, overvoltage category III. Rated for 50 Hz only. Mounts on DIN rail, occupies 2 width units, fits 70 mm installation depth. Mounting position is any; supply from top or bottom. Terminals accept 1.5 mm² to 50 mm² conductors. IP20 with distribution board installed and conductors connected. Finger and back-of-hand touch protection. Mechanical endurance is 10,000 switching cycles typical.","metaTitle":"Siemens 5SM3615-0KK SENTRON RCCB, 2-pole, 125 A, 300 mA, 230","metaDescription":"Siemens 5SM3615-0KK SENTRON RCCB, 2-pole, type AC, 125 A rated current, 300 mA residual trip, 10 kA SCCR, 230 V AC, DIN rail.
