The C60, a member of the UR family of protection and control systems, is a digital relay that provides complete breaker monitoring and control including breaker failure protection, synchrocheck, autoreclosure and power metering in one integrated package. It may be used as a standalone device or as component of an automated substation control system.

What's New in the C60:

Security Enhancements - Enabling NERC CIP compliance:
- Dual Permission access requiring live permission from both the user and from SCADA operators before settings can be changed or commands can be given to the relay
- Logging of user commands in the security audit trail relay - creates a record and sequence of events for troubleshooting and security auditing

Ambient Temperature Monitoring:
- Provides alarms when the ambient temperature exceeds hot extreme
