RFD-200 S3
Digital Timer
The RFD-200 S3 is a portable relay test set that delivers performance verification testing of electromechanical, electronic, and microprocessor-based protective relays in their operating installations. The RFD-200 S3 is a rugged test set suitable for testing a variety of protection relays operated in both indoor and outdoor environments. The unit’s ergonomic design and intuitive control panel layout make it ideal for first-time users who have little or no training.
