EARU EASP-PV-1000 SPD Replacement Cartridge Surge Protector Core

EARU EASP-PV-1000 SPD Replacement Cartridge Features and Specifications

The EARU EASP-PV-1000 cartridge insert provides surge suppression across seven distinct voltage levels—275V, 385V, 500V, 800V, and 1000V—accommodating both AC and DC applications in residential and industrial settings. Current ratings of 20kA, 30kA, 40kA, and 60kA mean this replacement core handles transient surges from lightning strikes, motor switching, and power factor correction capacitor discharge events. The DIN-rail mounted design integrates seamlessly into existing electrical cabinets, allowing technicians to swap worn cartridges without rewiring or system shutdown. Certified construction ensures compliance with IEC and UL standards for renewable energy installations, including solar PV systems where voltage fluctuations demand reliable protection. This SPD replacement cartridge insert extends equipment life and reduces total cost of ownership by isolating surge damage to replaceable components rather than forcing full unit replacement.
