The WRS4P32DC is a four-pole DC rotary isolator for solar PV applications, with a 1000V DC rated operational voltage and an IP66 enclosure. Its nominal dimensions are 98 × 189 × 110mm (W × H × D).

WCED specifies an enclosed thermal current of 32A at 40°C, reducing to 29A at 60°C. Thermal current is not a blanket switching-current rating for every load or wiring arrangement. Select the required DC duty and use the manufacturer's pole and bridging configuration for the circuit voltage and current.
