RCDs 4 Pole Type B

4 pole Type B RCDs offer comprehensive protection for three-phase systems with neutral by detecting AC, pulsating DC, and smooth DC leakage currents. Essential for modern applications such as electric vehicle charging points, photovoltaic installations, and equipment with variable speed drives or inverters, they ensure safety where conventional RCDs may not suffice. Designed for industrial and commercial environments, Type B RCDs provide reliable earth fault protection while fully isolating all conductors. Ensure high-spec safety and compliance with Type B 4 pole RCDs—available now at CEF.
