Delta LA 302 R Lightning Arrestor 120-250VAC 50-60Hz 3-Wire Single Phase LA302R

Description

Delta
AC Lightning Arrestor
3 Wire, Single Phase
LA 302R
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
LA302R
model for light duty 120-250VAC, single phase systems (three wire service) can be used for applications where two hot wires of a single 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
