Fault Counter 50 Amp Trip FC0050IR

Fault Counters (FCs) are designed to assist in locating recurrent momentary faults. Momentary faults are produced by tree boughs being blown into power lines, damaged or contaminated insulators, voltage surges, or insulation breakdown that clears upon power interruption of automatic reclosers.
FCs are line-powered from the alternating electric field surrounding the conductor. The FC counts and stores up to ten fault occurrences. The face of the FC is designed in the pattern of an analog clock face and uses a reflective red "hour hand" pointer to indicate the number of faults the FC has recorded. The stored count is erased without removing the FC from the line with a Fault Counter Reset Tool (FCRT).
The FC is easily and quickly installed using a single hot stick. The UV-stabilized housing and stainless steel clamping mechanism make it suitable for use in harsh outdoor environments.
