Feeder Protection Relay
FPS Series Relay
- Monitors voltage and current to provide a comprehensive package of 17 protective functions
- Modular system with integrated protection, breaker control, metering, and data-logging functions
Description
The Littelfuse FPS (Feeder Protection System) is a feeder protection relay that provides current, voltage, and temperature protection for feeder applications.
This overcurrent protection relay offers integrated breaker or contactor control, data logging, and a complete metering package. The FPS is typically used in processing, manufacturing, petroleum, chemical, mining, forestry, water, and waste treatment applications.
We are the exclusive NSW supplier of Littelfuse protection relays and controls for the protection, safe control and distribution of electrical power in industrial applications.
Overload – IEEE # 49, 51
Long-time overcurrent provides thermal protection for feeder or load.
Inverse-time overcurrent – IEEE # 50, 51
Coordination using IEEE and IEC Curves.
Definite-time overcurrent – IEEE # 50, 51
Instantaneous overcurrent to detect catastrophic failure.
Current unbalance/Phase loss/Phase reverse – IEEE # 46
Detects an open or high-impedance phase.
Earth fault – IEEE # 50G/N, 51G/N
Inverse and definite time. Early insulation-failure detection.
RTD temperature – IEEE # 38, 49
Optional protection (MPS-RTD module) for load-temperature monitoring.
Overvoltage – IEEE # 59
Limits stress to insulation.
Undervoltage – IEEE # 27
Detects a damaging brown-out condition.
Voltage unbalance – IEEE # 47
Detects unhealthy supply voltage.
Two setting groups
Minimises Arc-Flash hazards during maintenance.
Breaker control
Allows local and remote operation; reduces component count.
Metering
Displays the measured and calculated parameters.
Data logging
On-board 64-event recorder helps with system diagnosis.
Communications
Remotely view measured values, event records, and reset trips.
Conformal coating
Internal circuits are conformally coated to protect against corrosion and moisture.
