Overcurrent Trip Automatic Time Reset Indicator Series

The Fisher Pierce Series 1541/42/43 Faulted Circuit Indicators locate faults quickly and easily. The FCIs prevent repeated reclosing on faulted circuits which minimizes danger to service crews and damage to equipment.

The 1541/42/43 FCIs are available in single-, two-, and three-phase models. The FCIs are designed for underground applications to survive conditions of submergibility, salt spray, and extremes of hot and cold temperatures.

Fault registration and indication is provided by means of a high-intensity LED. The LED is directly integrated into the main sensor housing, mounted remotely, or connected through a fiber optic cable to a remote location.
