SURGE PROTECTIVE DEVICES
JSP – 120
HEAVY DUTY FOR SERVICE ENTRANCE APPLICATIONS
FEATURE S AND BENEFITS
• Listed to UL 1449 3rd Edition for a Type 1 and Type 2 SPD application.
• Fail-safe design with individually fused Metal Oxide Varistors (MOVs)
eliminating single point failure, protecting against both overcurrent and
overvoltage events.
• 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-year standard warranty with optional 15-year extended warranty.
