LPI’s surge filters are high-performance protection devices designed for operating voltages between 220–277 Vac. Incorporating advanced SST150B Bluetooth technology, they provide both primary and secondary protection across a current range of 32 A to 125 A, available in both single and three-phase options.

These filters feature an encapsulated spark gap and SST150B technology, ensuring reliable performance even under fault or overvoltage conditions—up to 480 Vrms for 200 A filters and above. With a robust three-stage protection system, they offer superior defense for sensitive electronic equipment.
