Operational Overview
The CSFPI operates by indicating a fault condition
when the current exceeds set trip current settings.
The cable-mounted sensor triggers a signal to the
indication unit, activating a red flashing LED and relay
contact.
Automatic reset mechanisms, including time passage,
external input, or 230V AC recovery, ensure
continuous operation.
