Delta LA603 AC Lightning Arrestor, Three Phase (4-Wire)

Delta
AC Lightning Arrestor
3 or 4 Wire, Three Phase
High Voltage, 440-600VAC
LA 603

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.

DELTA ARRESTORS:

• employ a non-conductive base to prevent a blown arrestor from creating a shock hazard
• do not cover adjacent equipment with carbon dust on failing, preventing damage to other equipment
• always fail "clear" to permit continued use of the power system
• are 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
• feature extra long leads to ease installation
• have locknut and bushing furnished
• are available in a variety of voltages or number of poles
