Introduction
The OVRHLD Surge Protective Device (SPD) is
designed for protection of downstream distribution
equipment and wiring as well as most sensitive
electrical and electronic loads from the effects of
overvoltage transients that might result from
lightning, induction, and switching of loads or
capacitor banks. This is a light duty device and
should be used in minimum to moderate lightning
environments, or in high lightning areas if used
downstream of a primary, heavier duty protection
device installed at service entrance.
Product features
– Listed to UL 1449 4th edition for Type 1 SPD
applications.
– Multiple Metal Oxide Varistors (MOVs), with
individual overcurrent fusing and thermal
disconnects for each MOV.
– LED indicates proper functioning of MOVs.
