LA601 - For 440-600 Volt Single
Phase 2 Wire Service

Rated voltage 240-480-600 Volt, two wire service. Used when one hot wire of a three phase system is to be protected; one wire for a control circuit, or three arrestors for protecting three phases.

INSTALLATION:
Fasten arrestor in place. Use a Delta mounting bracket, part # MB, a pipe strap, or a knockout hole. Connect the black wire to the hot line at any convenient point load-side of an existing fuse or circuit breaker. Connect the white wire to an existing ground system and the grounded metal frame work of the equipment to be protected, or make a ground source per NEC Article 250.

Electrical work is hazardous. Bad connections can result in fire, injury or death. Installation must only be done by qualified electricians.

In the event that a lightning discharge is so powerful that something has to be destroyed, the 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 arrestor in any approved electrical box will prevent accidental contact with a damaged unit.
