LA303 - for 250 V, Three Phase, 3 or 4 Wire Service
Rated voltage 250 Volt, three or four wire service. Used when three hot wires of a three-phase system are to be protected.
Rated voltage 250 Volt, three or four wire service. Used when three hot wires of a three-phase system are to be protected.
INSTALLATION:
Fasten arrestor in place. Use a Delta mounting bracket, part # MB, a pipe strap, or a knockout hole. Connect the black wires 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 framework of the equipment to be protected or make a ground source per NEC Article 250.
