Singleunit 2P DC Surge Protective Device for up to 1000 V DC, 2040 kA discharge capacity. Designed as a residential lowvoltage arrester to protect DC circuits from transient overvoltages. Key benefits Protects DC systems from surge events by diverting excess voltage away from sensitive equipment, reducing the likelihood of component failure. Wide discharge capacity specified at 20 to 40 kA to handle a range of surge magnitudes common in residential and small commercial installations. Rated for DC systems up to 1000 V, making it suitable for voltage DC arrays and battery strings. Simple singleunit format for straightforward selection and replacement in existing installations. Main features Product type: SPD, single piece, 2pole DC configuration. Voltage rating: up to 1000 V DC. Surge handling: 2040 kA discharge capacity. Function: lowvoltage arrester designed to limit transient overvoltages on DC lines. Construction: durable insulated housing sized for electrical installation environments and designed for reliable operation over time. Compatibility and applications Compatible with DC power systems operating at or below 1000 V DC, and with twopole DC circuits. Commonly used in residential photovoltaic arrays, battery energy storage systems, and DC distribution panels where transient protection is required. Suitable for retrofitting into existing DC installations or inclusion in system builds that require a single surge protection device. Performance and installation notes Designed to respond to transient surges and divert surge energy away from connected equipment. Compact physical form facilitates installation in standard electrical enclosures; check local wiring layout and space for fitment. Intended for use by qualified electrical installers in accordance with local electrical codes and practices. Practical use scenarios 1. Residential solar array: installed near the DC combiner or battery inverter input to protect string inverters and charge controllers from lightninginduced or switching transients. 2. Home battery storage: placed on battery DC bus to reduce the impact of surge events on battery management systems and inverters. 3. Offgrid DC distribution: used in small offgrid systems to safeguard DC lighting, controllers, and converters from transient voltage spikes. This singlepiece 2P DC SPD offers a focused solution for protecting DC circuits up to 1000 V with a 2040 kA surge handling range. Consider system voltage and wiring configuration when selecting and installing the device.
