FEEDER PROTECTION UNIT FPU-16 FEEDER PROTECTION UNIT

THE FPU-16 FEEDER PROTECTION UNIT The FPU-16 is a microprocessor-based feeder protection unit with programmable trip-and-alarm set points for phase protection, ground-fault protection, and current unbalance. Features of the FPU-16 include an operation counter, front-panel programming, independent trip-and-alarm relays, and an isolated analog output.

FPU-16 FEEDER PROTECTION UNIT Compact design-1/4 DIN size Temperature rating of -40°C to 60°C Panel or surface mount Supply voltage range of 85 to 135 Vac Program-change lockout

FPU-16 FEEDER PROTECTION UNIT Separate trip and alarm contacts - Fused - Form “C” - Fail-safe or non-fail- safe operation Plug-in terminal blocks

Units can be ordered with optional 120 Vac or 240 Vac and 50 or 60 Hz. There is also an optional DC power supply. 5-6-7 - are the form “C” trip relay. It is 10 A rated and fused at 8 A. Relays can be configured to operate in the fail-safe or non-fail-safe mode. 8 - System ground 9 - Key Pin. High voltage lower block cannot be plugged into low voltage upper terminals. 10-11-12 - Form “C” alarm relay. 23 -24 - isolated analog output or RS-485. 21-22 - Input for Earth-fault CT. 20-21 - Program enable. These pins must be connected to allow program changes. 17-18-19 - Input for RTD or Thermistor. 13-14-15-16 - ICT-2 Interface CT input. ICT-2 shown on the next slide.

ICT-2 INTERFACE CT Provides mounting flexibility Mounting ICT-2 close to CT’s provides: - Less signal loss -Eliminates open CT hazard
