2P 40KA PV Surge Protection Device

A two-pole surge protective device built for photovoltaic system resilience, rated for 1000V DC maximum continuous voltage and capable of discharging up to 40kA (8/20μs). Its protective response limits residual voltage to 3.8kV, safeguarding sensitive inverter inputs and string-level electronics. The housing is manufactured from flame-retardant polycarbonate, providing mechanical durability and compliance with IP20 for dust protection in indoor mounting locations. Installation conforms to widely adopted 35mm DIN rail standards—compatible with enclosures used across UK domestic, commercial, and agricultural solar farms. Unit dimensions support high-density panel layouts without airflow obstruction or clearance issues.
