The WCED WRP440C-030 is a 40A, C Curve, 4 Pole Type A RCBO designed for three-phase circuits where you need combined overload and residual current protection in one device. It suits applications with higher inrush demand such as EV-related installs, motors, HVAC equipment, commercial distribution and selected renewable energy board setups.
As part of the WRP 3P+N RCBO range, this unit provides 30mA high immunity protection with switched live and neutral for dependable fault disconnection and safer circuit isolation. Built to IEC/EN 61009-1 with a 10kA breaking capacity, it gives electricians a solid option for demanding domestic and commercial installs.
Installer Tip: Use the 40A C Curve model where circuits experience higher start-up currents. Where a circuit has more straightforward resistive loads, a B Curve device may be the better fit.
