The Type A residual-current element detects pulsating DC fault currents — the kind rectifier-fed loads like washing machines, LED drivers, or VFDs can generate — as well as sinusoidal AC. With a 30 mA trip threshold it meets the person-protection requirement for socket-outlet circuits in most residential and commercial codes. The C characteristic (63 A In) handles inrush from motor-starting or capacitive loads without nuisance tripping, while still protecting the final circuit against sustained overload. Lifecycle stage is current. That means Siemens still manufactures this order code; no phase-out notice or last-time-buy date has been issued. The 1P+N width (two modules) fits standard distribution boards. Supply side connects to the top terminals; load side exits the bottom. The neutral bar is integral — no separate neutral link to wire. Torque the terminals to the value marked on the device side; over-torquing cracks the housing and voids the rating.","metaTitle":"Siemens 5SU9346-7CN63 RCBO, 6 kA, 1P+N, Type A, 30 mA, C-Cha","metaDescription":"Siemens 5SU9346-7CN63 RCBO, Icn 6 kA, 1P+N, Type A, 30 mA, C-Char, In 63 A, Un AC 230 V.
