|Delta Lightning Arrestors|
Cat. No. DL- 53.41xx
Delta lightning arrestors
have a maximum current rating of 60,000 amps and 2,000 joules per line. Response
time is 25 ns to clamp 50,000 amps. Mounts easily in a 1/2" knockout.
Install the DC version for surge protection on wires coming from a
PV array, DC wind generator or DC hydroelectric turbine. Use the 600 VDC
unit for high-voltage grid-tie PV arrays. Lightning protection can
be installed in a combiner box, DC load center or grid-tie inverter. The
AC versions can be mounted in you AC load center to protect 120/240 VAC wiring
running outside of the building, to generators, pumps or outbuildings. All
units are waterproof.
Why Have Surge
Photovoltaic, wind and hydroelectric systems usually have long runs of exposed
wire that can pick up surges from lightning, even if the lightning strike
is not nearby. These power surges can damage sensitive electronic components
in meters, charge controllers and inverters. Surges can also damage
telephone, audio and video equipment connected to the power system. It
is a good idea to install surge protection on all incoming wires in the system,
including incoming PV, wind ao hydroelectric power lines, AC generator lines,
telephone and antenna leads. Proper grounding is absolutely necessary
for lightning protection to be effective. In the event of a direct strike,
damage may occur, even with surge protectors installed.
Type 1 heavy duty surge protectors are recommended when a direct lightning
strike is possible on the installation.
