1pc SPD 2P DC 2040kA 500V House Surge Protector Protective Lowvoltage Arrester Device Key benefits Protects DC equipment from transient overvoltages by diverting surge energy away from sensitive components. Wide discharge capability of 2040kA to handle frequent or energy surge events. Rated for DC systems up to 500V, suitable for common residential and small commercial lowvoltage DC installations. Twopole configuration provides simultaneous protection for both conductors in a DC circuit. Singlepiece device for straightforward parts sourcing and replacement. What it does Acts as a lowvoltage arrester that limits voltage spikes on DC lines and reduces the chance of damage to inverters, charge controllers, batteries, and other DCpowered equipment. Designed for continuous DC operation at system voltages up to 500V. Key features and attributes Model: SPD 2P DC Quantity: 1pc Protection rating: 2040kA discharge capacity Voltage rating: 500V DC Poles: 2P for dualconductor DC circuits Construction: durable, compact housing for installation in DC distribution points Performance: rated to absorb energy transient surges while operating within lowvoltage DC systems Compatibility and typical integration Compatible with DC arrays and circuits with nominal voltages up to 500V. Suitable for integration into combiner boxes, DC distribution panels, or inline protection schemes where twopole DC protection is required. Works with battery storage systems, solar inverter DC inputs, and other lowvoltage DC equipment. Practical use scenarios Residential solar array: Install near the DC combiner or inverter input to reduce the impact of lightninginduced or switching transients on the inverter and downstream equipment. Offgrid battery system: Place between solar charge controllers and battery banks to help limit surge exposure to batteries and power electronics. Small DC power distribution: Use in DC distribution panels for cottage, workshop, or telecom backup power to provide coordinated surge diversion across both conductors. What is included One 2pole DC surge protective device rated 2040kA, 500V. Notes for selection Choose this device when you need twopole DC surge protection for systems with voltages up to 500V and surge events within the 2040kA range. Ensure component compatibility with your system voltage and wiring layout prior to installation.
