Protective Trip and Warning Functions
Introduction
This chapter provides detailed information about the protective trip and warning
functions of the E300Electronic Overload Relay. The protective trip and
warning functions are organized into five sections:
• Current-based
• Voltage-based
• Power-based
• Control-based
• Analog-based
This chapter explains the trip and warning protection features of the E300
Electronic Overload Relay and the associated configuration parameters.
Current-based Protection
The E300 Electronic Overload Relay digitally monitors the electrical current that
is consumed by an electric motor. This electric current information is used for the
following protective trip and warning functions:
• Overload Trip/Warning
• Phase Loss Trip
• Ground Fault Trip/Warning
• Stall Trip
• Jam Trip/Warning
• Underload Trip/Warning
• Current Imbalance Trip/Warning
• Line Under Current Trip/Warning
• Line Over Current Trip/Warning
• Line Loss Trip/Warning
