The TPSESA3 is a MOV (Metal Oxide Varistor) based hardwired Secondary 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 TPSESA3 is a three pole, three phase, four wire arrester intended to protect 480 VAC systems and has four 18” long, 12 AWG multi-strand leads that are color coded for ease of installation.
The epoxy encapsulated arrester is designed to be easily installed in any position indoors or outdoors utilizing the integral ½ “ NPT threaded nipple and supplied metal lock nut. The housing is molded from flame retardant plastic that is other 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 Siemens Surge Arrester 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. These devices utilize a single MOV per pole to reduce the potential load balancing/sharing problems during operation.
