The PGR-4300 Generator Ground-Fault Relay provides a simple method for detecting a ground-fault condition on generators without the need for current transformers (CTs). This greatly simplifies the installation. In addition, it is compatible with both three- and four-pole transfer switches. This relay also monitors the neutral-to-ground path for continuity. The PGR-4300 is ideal for any generator or application where there is not sufficient space to install CTs.

Features & Benefits:

 

• No CTs required: Saves space and simplifies installation
• Adjustable pickup (100-1200 A): Adjustable trip setting provides a wide range of protection and allows system coordination
• Adjustable time delay (0-1.0 s): Adjustable trip delay allows quick protection and system coordination
• Output contacts: Form C ground-fault output contacts for alarming or tripping purposes
• Analog output (0-1 mA): Provides means for connecting to an optional meter (PGA-0500) or control system
• N-G continuity alarm: Monitors neutral-to-ground integrity and alarms if ground path becomes open circuit
• Passive filtering: Eliminates nuisance tripping
