DESCRIPTION

The HE4803 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 HE4803 is a three phase, four wire surge arrester intended to protect 277/480 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 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 HE4803 has four 18" long, 12 AWG multi-stranded leads that are color coded for ease of

installation.

The HVPSI HE4803 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 HE4803 utilizes a single MOV per pole to reduce the potential load balancing/sharing problems during operation.
