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 LA603 high voltage model for 240/480/600VAC, three phase systems (3 or 4 wire service) can be used for applications where three hot wires of a three phase system are to be protected.

  • based on a silicon material to provide quicker operation at lower conduction resistance
  • will pass a large number of high-energy surges and half-cycle spikes prior to failing
  • extra long leads to ease installation
  • locknut and bushing furnished
