Joslyn's Surgitron III - AC Leaded Medium Duty SPD

Multiple Protection

Joslyn medium duty knockout (K/O) products can be mounted to panels and/or brackets for in-wall installation and offer protection against multiple lightning strikes or other induced voltage surges. The surge current capability of this family exceeds the heaviest surge described by ANSI/IEEE C62.41-1991 (Location category C3). While not as robust as the higher kA Surgitron models, these medium duty protectors also have an exceptional track record of protection and reliability across 25 years of service. Tens of thousands of field installations have proven these products as reliable work horses that will protect your load electronics for a long time.
