Product: 2P DC Surge Protective Device (SPD) LowVoltage Arrester Key benefits Protects DC and lowvoltage circuits from transient overvoltage events to reduce equipment damage and downtime. surge discharge capacity, rated from 20KA to 40KA, absorbs large transient currents and redirects them away from sensitive electronics. Flexible voltage compatibility with available nominal DC ratings of 500V, 600V, 800V, and 1000V, and reference AC values of 275VAC and 385VAC for related lowvoltage applications. Twopole design for straightforward protection of positive and negative DC conductors in common DC power systems. Compact form and sturdy construction for reliable installation in distribution boxes and power cabinets. Product attributes Model type: 2P DC SPD, lowvoltage arrester device. Size: Gray Surge. Color: 800VDC (model/nominal voltage designation available in other ratings listed above). Surge current capability: 20KA to 40KA per pulse. Voltage options: 500V DC, 600V DC, 800V DC, 1000V DC; reference AC ratings 275VAC and 385VAC. Function: Diverts and clamps transient overvoltages to protect downstream equipment. Compatibility: Designed for DC power systems, photovoltaic arrays, battery banks, inverter inputs, and other lowvoltage DC installations that require twopole surge protection. How it solves common problems Prevents transient spikes from damaging inverters, charge controllers, batteries, and DC distribution components by providing a controlled path for surge energy. Reduces service interruptions and costs by minimizing the chance of component failure from lightninginduced or switching transients. Offers clear voltage and discharge capability options so installers can match the SPD to system nominal voltage and expected surge exposure. Practical applications and use scenarios Residential solar array protection: Install at the DC combiner box or between PV strings and the inverter to protect inverter electronics and downstream DC wiring from surge events. Battery energy storage systems: Place at battery string junctions and DC distribution panels to safeguard charge controllers and power electronics during switching surges or external transients. Small commercial and telecom DC power cabinets: Use as part of a coordinated surge protection scheme to protect DC equipment racks and sensitive communications gear. Installation and selection tips Select the SPD nominal voltage that matches your system DC voltage (500V, 600V, 800V, or 1000V) for correct operation. Confirm the required surge discharge capacity based on site exposure and coordination with upstream protection; available ratings span 20KA to 40KA. Mount the device in a protected enclosure close to the equipment to be protected, and follow standard wiring practices for twopole DC protection. What sets this SPD apart Clear range of nominal voltages and surge current ratings to suit common lowvoltage DC applications. Twopole configuration for complete DC conductor protection in a single device. Practical design intended for straightforward integration into residential, commercial, and industrial DC systems.
