Type b rcd symbol. RCD protection is life-saving and protects against fires.

Type b rcd symbol. Residual current devices (RCDs) prevent you from receiving fatal electric shocks. residual current device 1P residual current device selective type AC - for residual alternating currents type B - for residual alternating, pulsating and direct currents type A - for residual alternating and pulsating direct currents delayed shutdown. Aug 4, 2022 · Type B RCD are intended to be used for loads with three-phase rectifier, such as variable speed drives, PV system, EV charging station and medical equipment. See the symbols for Type AC, Type A and Type B RCDs and when to use them. RCD protection is life-saving and protects against fires.
