Surge Protective Device SPD DC 140V 2P 80kA Overview A lowvoltage surge arrester designed for DC systems. The SPD DC 140V 2P 80kA diverts transient overvoltage events away from sensitive equipment and reduces the impact of voltage spikes on connected circuitry. Key benefits discharge capacity: 80kA rating for handling large transient currents common in power system surges. Designed for DC applications: Nominal voltage 140V DC with twopole configuration to suit bipolar or positivenegative DC circuits. Protects connected equipment: Minimizes the effect of transient events on inverters, controllers, batteries, and other DC devices. Compact and installationfriendly: Intended for integration into lowvoltage distribution and control panels where space is limited. Durable construction and reliable operation: Built to operate under repeated transient events while maintaining consistent performance. Function and performance Primary function: Clamp and divert surge energy away from the protected circuit during transient overvoltage occurrences. Performance focus: Rapid response to voltage spikes and a maximum discharge capability to handle severe transient currents. Compatibility Intended for lowvoltage DC systems operating around 140V DC. Suitable for integration with solar string arrays, battery banks, DC distribution panels, and DCpowered industrial or telecom equipment. Practical applications Solar photovoltaic systems: Install at combiner boxes or DC distribution points to reduce the impact of lightninginduced or switching transients on inverters and downstream electronics. Battery energy storage and offgrid power systems: Protect charge controllers, battery management systems, and DC loads from surge events during switching or grid disturbances. Telecom and industrial DC installations: Provide surge mitigation for DC supply lines feeding remote radio units, control equipment, and monitoring devices. What to consider when selecting Verify system voltage and polarity to match the 140V DC nominal rating and twopole configuration. Confirm discharge requirements; the 80kA rating indicates capability for energy transient events. Check physical space in the distribution panel or enclosure for integration. Technical summary Model: SPD DC 140V 2P 80kA Function: Surge Protective Device / Lowvoltage arrester for DC circuits Nominal voltage: 140V DC Poles: 2 Discharge capacity: 80kA This SPD is intended for use where reliable transient suppression in lowvoltage DC systems is required. Review system parameters and installation requirements prior to fitting to ensure compatibility with site equipment.
