DESCRIPTION
The HE500 is a MOV (Metal Oxide Varistor) based hardwired Secondary Surge Arrester, often referred to as a Lightning
Arrester. The device is designed to protect electrical equipment from damaging effects of Spikes (+) and Notches (-)
caused by lightning, utility switching, insulation arcing, electrical motor cycling, and other large or sudden changes in
electrical power flow on incoming AC power lines.
The HE500 is a two pole, single phase, three wire arrester intended to protect 120/240 VAC systems. The epoxy
encapsulated arrester is designed to be easily installed in any position indoors or outdoors utilizing the integral 1/2" NPT
threaded nipple and supplied metal lock nut. The HE500 replaces the HE500S.
The housing is molded from flame retardant plastic that is both weather and UV resistant, and complies with the UL
standard for strength and flame resistance properties. The arrester is sealed with UL component recognized epoxy
potting compound. The HE500 has three 18" long, 12 AWG multi-stranded leads that are color coded for ease of
installation.
The HVPSI HE500 is ideal protection for outdoor lighting and pole lamps, panel boards, oilfield pumps, workshops,
irrigation and sump pumps, refrigeration systems, farm equipment including milking machines and poultry processing
equipment, electric motors and controls, heat pumps and air conditioning equipment and many other electrical devices.
The HE500 utilizes a single MOV per pole to reduce the potential load balancing/sharing problems during operation.
