Its 35 mm internal diameter accepts the main conductors, while the 80 A rated operational current and 30 mA minimum residual current sensitivity suit it for downstream RCD coordination in distribution boards. Rated for up to 720 V AC at 50 or 60 Hz, with a 4 kV surge voltage withstand, this transformer connects via screw-type terminals accepting 0.13 to 2.1 mm² conductors. Operating temperature range spans -20 °C to 70 °C, with up to 95% humidity, making it suitable for unconditioned electrical rooms. ## Integration notes Mounts on DIN rail inside a panel. The 35 mm internal diameter accepts up to 80 A main conductors — typically a single cable or busbar per phase. Maximum wire length from the transformer to the connected RCD or evaluation unit is 10 m; keep the twisted-pair run short to avoid nuisance tripping from induced noise. Screw terminals accept 0.13 to 2.1 mm² — fine for the secondary wiring. Torque to the manufacturer's specification (not listed here; follow the nameplate). The Type A design means it will detect smooth DC residual currents up to 6 mA plus AC, which covers modern electronics with half-wave rectification.","metaTitle":"Siemens 5SV8702-0KK SENTRON Summation CT, 80 A, 35 mm ID","metaDescription":"Siemens 5SV8702-0KK SENTRON summation current transformer, Type A, 80 A rated, 35 mm ID, 720 V AC max, IP20.
