The WPEVCU63CSP is a heavy-duty IP65 EV connection unit fitted with a 63A C Curve MCB, 100A isolator, and integrated Type 2 Surge Protection Device (SPD). It provides reliable overload protection, circuit isolation, and surge defence for EV chargers, solar PV systems, and external distribution circuits.
With a 63A rating and C curve tripping characteristic, this unit is designed for light commercial chargers, multiple domestic charge points, or renewable installs where high inrush currents are expected. The IP65 enclosure ensures it is weatherproof and compliant with BS 7671:2018 (Amendment 2).
Installer Tip: Use the 63A C Curve variant for high-demand EV circuits or small commercial installs where multiple chargers or PV inverters are connected. Always size cables correctly for the higher load.
