In the event that a lightning discharge is so powerful that something has to be destroyed, the delta arrestor will take the damage. When sufficient heat and stress causes failure, a one inch hole will open at the bottom of the enclosure. Hot silica and plastic bits will be expelled. Installing the delta arrestor in any approved electrical box will prevent accidental contact with a damaged unit.


The delta lightning arrestor installed in the breaker box above helps to protect your delicate sensitive electronic equipment in your entire home or establishment from daily small surges like air conditioners or refrigerators turning on or off. The delta surge protector installed in the telephone box below helps to protect your telephone, computer, or fax lines in your entire home or establishment from all types of surges like lightning.
