Balanced Operation

C4B1S-BAL Series

Balanced Operation with Self-Resetting Current Limiters

Description:

The C3B1S-BAL & C3B1FS-BAL premium series of 5 pin solid state protector modules are designed to provide superior transient and power fault protection for most standard telephone line applications. The balanced configuration provides the best protection against line to line metallic surges where the transient on one side slightly lags the other. The characteristics of the solid state protector are far superior to gas tube technology in speed of response to faults and are virtually immune to overshoot, aging, and failure due to repeated tripping within rated limits. The C4B1S-BAL & C4B3S-BAL with PTC (positive temperature coefficient) versions include fast acting, self resetting current limiters. These are especially useful where extra protection against "sneak current" type faults is desirable.
