SymCom 80 Reverse-Phase Relay/171-528V/Fast-On Terminals 3-Phase Voltage Monitors

The Model 80 is designed to continuously monitor for ABC phase sequencing of 190-480VAC, 3-phase systems. Critical applications include fan motors, scroll compressors, grinders, conveyor systems, elevators and escalators. A solid-state sensing circuit energizes a Form C relay and illuminates an LED indicator when the proper phase sequence is applied.

SymCom 80 3-Phase Voltage Monitor Features

• Protects 3-phase motors from phase reversal• 0.5 second response time• Relay status LED• Automatic reset• CSA approved for use in Canada and US• 5-year warranty• Made in the USA
