30mA residual current protection
63A B-Type RCD – protects against smooth and pulsating DC earth leakage
Installer Tip: A 40A C Curve is widely used for larger inductive loads such as HVAC compressors
it is best suited to resistive load applications such as large socket outlet groups
3-Pole Type A RCBO – 20A C Curve 30mA 10kA (WRT320C-030) PME Fault Detection 30mA residual current protectionThe WRT320C 030 is a 3 pole Type A RCBO combining residual current protection and overcurrent protection in a compact 3 module device. Rated at 20A with a C curve and 30mA sensitivity, it provides reliable protection against overload, short circuit, and earth leakage faults across all three phases. This RCBO is designed for three phase commercial, industrial, and advanced residential installations where modern electronic loads are present. Type A
