3-Pole Type A RCBO – 40A B Curve 30mA 10kA (WRT340B-030) A Type EV RCBO Kit and Type B RCDThe WRT340B 030 is a 3 pole Type A RCBO designed for three phase circuits requiring combined residual current and overcurrent protection at a 40A rated current. With a B curve characteristic and 30mA sensitivity, it provides reliable protection against overload, short circuit, and earth leakage faults in a compact 3 module DIN rail format. Type A residual current protection allows detection of AC residual currents and pulsating DC components, making
