DESCRIPTION

The HE850 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 HE850 is a three phase, four wire arrester intended to protect 220/380 VAC systems. The epoxy

encapsulated arrester is designed to be easily installed in any position indoors or outdoors utilizing the integral 1/2"

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 HE850 has four 18" long, 12 AWG multi-stranded leads that are color coded for ease of

installation.

The HVPSI HE850 is ideal protection for outdoor lighting and pole lamps, panelboards, 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 HE850 utilizes a single MOV per pole to reduce the potential load balancing/sharing problems during

operation.
