Balanced Operation
Description:
The 3B1S-300 & 3B1FS-240 premium series 5-pin
solid-state protector modules are designed to provide superior transient and
power fault protection for most standard telephone line applications.
These solid-state modules are particularly suited to applications that
require the protection of very sensitive digital equipment due to their
nanosecond reaction time. The balanced configuration of these modules
provides the best protection against a line-to-line, metallic surge, where
there is a large voltage differential between the two sides of the
circuit. The characteristics of the solid-state protector are far
superior to gas tube technology in speed of response and are virtually immune
to overshoot, aging, and failure due to repeated tripping within rated
limits.
The 4B1** 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 competition's heat coil solution which requires that
the module be replaced after each sneak current event.
