Protection and safety
OVRHSP/OVRHSR Facility Wide Protection – 4,000A and below

• Listed to UL 1449 4th Edition for Type 1 and Type 2 SPD applications.
• Fail-safe design with individually fused Metal Oxide Varistors (MOVs) eliminating single
point failure, protecting against both overcurrent and overvoltage events.
5
• 200kAIC short circuit rating permits direct bus connection to most electrical services.
• Low let through voltage ensured by the lowest possible impedance path to ground and
equal current sharing during surge events.
• All weather sealed, powder-coated NEMA 4/IP65 housing is designed for any orientation
and indoor/outdoor applications.
• 10 years standard warranty.
