Catalog 1308242 Issued 3-03 AGASTAT VMA series 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. File E60363 Users should thoroughly review the technical data before selecting a product part number. It is recommended that user also seek out the pertinent approvals files of the agencies/laboratories and review them to ensure the product meets the requirements for a given application.
