Delta LA-AC-3PH Lightning Arrestor

Delta LA-AC-3PH Lightning Arrestor-AC, 3 Phase

Rapid response, high current Delta Lightning Arrestors help prevent damage to computers and other electronic equipment. The Delta LA Series handles the big surges, like lightning up to 50,000 amps, passing them harmlessly to the ground.

While it is not possible to achieve 100% protection, Delta units will greatly reduce problems due to lightning, power surges and voltage spikes. The LA303 model for 110/208/250VAC, three phase systems (5 wire service) can be used for applications where three hot wires of a three phase system are to be protected.
