Modular surge protective device capable of handling the high-impulse, potentially damaging transients commonly found at the service entrance or distribution panels. Its robust design allows for placement and protection in the most severe exposure locations.
Surge current capacity—100,000 to 400,000 Amps per phase
Replaceable modules ensure protected mode flexibility
All voltage and phase configurations
Unique MOV/Silver link fuse array enables the IH Series to deliver the industry’s most robust design. Coordination between fuse gauge and MOV ensures repeatable strike performance
Status indication includes: audible alarm, form C contact, and internal/external status indication
Optional equipment includes rotary disconnect, surge counter, NEMA 3R, 4 or 4X enclosures
