Description
This is a premium series 5 PIN solid state protector module that is designed to provide superior transient and power fault protection for most standard telephone line applications. These solid state modules are suited to applications that require the protection of sensitive telephone equipment due to their nanosecond reaction time. The characteristics of the solid state protector are far superior to gas tube technology in speed and are virtually immune to overshoot, aging and failure due to repeated tripping.
The 4 - Series features PTC (positive temperature coefficient) technology. These optional self-resetting current limiters provide effective protection from 'sneak current' faults. The PTC is vastly superior to the heat coil solution, which requires that the module be replaced after each 'sneak current' event.
