Protector Series


The PRO I is a solid state, heavy-duty lightning arrestor and transient voltage surge suppressor that is installed at the indoor service panel or on the weather head where the utility permits. When a destructive lightning surge enters the wiring, the PRO I clamps the voltage to a safe level in nanoseconds, absorbing the potentially dangerous pulse and dissipating it harmlessly to ground. Having protected your valuable electronic circuitry, the PRO I immediately self-restores, ready to protect against the next surge.

The PRO I also protects against power switching surges and induced AC surges that are proven to be extremely destructive to computer and other electronic and electrical equipment. It is far superior to the air-gap devices which typically allow 2000 volts to pass through and damage electronic equipment. The PRO I is completely encapsulated, weatherproof and built to withstand great impact without impairing its ability to protect against surges. The protector operates on AC power, for single phase 120/240V, three wire grounded neutral service
