Single Phase, Plug-in
Undervoltage Relay
• Automatic reset minimizes equipment downtime.
• Fixed pickup point prevents low voltage start-up.
• Adjustable dropout point protects against undervoltage
operation.
• Locking potentiometer maintains selected set point.
• Delayed dropout prevents nuisance tripping.
• Plug-in mounting for easier installation.
• Built-in protection against polarity reversal.
• LED indicates normal voltage condition.
