HIGH-SPEED, HIGH-CURRENT SURGE PROTECTORS
PMT(301) Series
DESCRIPTION
CP Clare's PMT(301) Series surge protectors (350-3500V) provide a high level of protection from high-speed, high-current transient surges. These devices are constructed using a proprietary semiconductor junction process, which results in nanosecond response times combined with peak current ratings in excess of 10kA.
