Series: PGR-2601
Ground-Fault Relay for Ungrounded DC systems
The PGR-2601 provides sensitive ground fault protection without the problems associated with nuisance tripping. Applications range from industrial 24Vdc control circuits to 800Vdc automated transportation systems.
Features/Benefits:
• Sensitive 1- to 20-mA trip setting provides a wide range of
low-level protection and 50-ms to 2.5-s trip delay allows
quick protection
• Form A and Form B ground fault alarm contacts
• Non-volatile trip memory retains trip state
• Analog output for external metering
• Selectable fail-safe or non-failsafe operating modes
• No calibration required
