Enforcer Series

For more details call:


The ENFORCER is a solid state, heavy duty lightning arrestor and transient voltage surge suppressor that is installed at the indoor service entrance panel or on the weather head where the utility permits. When a destructive lightning surge enters the wiring, the ENFORCER 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 ENFORCER immediately self-restores, ready to protect against the next surge.

The ENFORCER 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 air-gap devices which typically allows over 2000 volts to pass through and damage electronic equipment.

The ENFORCER is completely encapsulated, weatherproof and built to withstand great impact without impairing its' ability to protect against surges.

The ENFORCER operates on standard AC power, single-phase 120/240 volt (ENFORCER1) or 240/480 volt (ENFORCER IV). It can also protect three phase circuits where the line to ground 60Hz voltage does not exceed 175 volts (ENFORCER II) or 600 Volts
