The SPD150 / SPD60 surge protection devices incorporate the latest in protection technology and ease of installation. These devices are designed to dissipate the harmful energy produced by lightning strikes and other power line transients commonly found in HVAC installations. These voltage transients can be very damaging to the equipment, shortening its life and reducing its efficiency.
