XLSPDPV Surge Protective Device SPD Size: 2P 500V Model and ratings: XLSPDPV 2P DC 500V 800V 3P DC 1000V 20KA40KA Key benefits Protects equipment from lightning strikes and sudden voltage surges, reducing the risk of damage to electrical systems and connected load devices. Stable performance and longer service life thanks to precision electronic components and quality copper fittings for reliable conductivity. Safe and easy to maintain modular construction made from PC flame retardant material. Wide range of voltage options and discharge capacities to match different DC system requirements. What this device does Acts as a surge arrester to divert and dissipate transient overvoltages on DC lines before they reach sensitive components. Helps maintain steady operation of inverters and other power conversion equipment by limiting surgerelated disturbances. Available in 2P and 3P configurations and suitable for systems with rated DC voltages shown in the model listing. Important attributes Function: Surge protection for DC power systems and load devices. Compatibility: Designed for DC applications including photovoltaic arrays, inverter inputs, battery systems, and DC distribution lines that match the listed voltage ratings. Size and models: 2P 500V variant included; reference model listing XLSPDPV 2P DC 500V 800V 3P DC 1000V 20KA40KA. Material: PC flame retardant housing and copper fittings for improved conductivity and safer use. Performance: Discharge capacity range 20kA to 40kA depending on model; precision components for stable, longlasting operation. Design: Modular build for straightforward installation, inspection, and replacement of modules when needed. Typical applications Rooftop or groundmounted photovoltaic string protection at the combiner box to guard inverters and downstream equipment from lightning induced surges. Offgrid and hybrid battery systems to protect charge controllers and inverter inputs from transient overvoltages. Commercial or industrial DC distribution circuits where surge protection is required for critical control and power electronics. Installation and use notes Select the model with the correct voltage rating and pole configuration for your DC system. Modular design simplifies servicing and replacement of units without extensive downtime. Use as part of a coordinated protection scheme with appropriate grounding and upstream or downstream protective devices.
