SymCom 250A-MET MotorSaver
SymCom 250A-MET - In Stock
Is an auto ranging voltage monitor designed to protect 3-phase motors regardless of size. It is used on 190-480VAC, 50 to 60Hz motors to protect the motors from damage caused by single phasing, low voltage, phase reversal, voltage unbalance and also high voltage, Right Form C relay energizes only on RP.
SymCom 250A-MET has two Form C relays that operate independently of each other. The left-hand relay will energize when voltage conditions are good and de-energize when a fault condition is detected. The right-hand relay will only energize during a reverse-phase condition.
Unique microcontroller-based voltage and phase sensing circuit constantly monitors the three phase voltages to detect harmful power line conditions. When a harmful condition is detected, the MotorSaver’s output relay is deactivated after a specified trip delay. The output relay reactivates after power line conditions return to an acceptable level for a specified amount of time (restart delay), unless the unit is in the manual reset mode. The trip delay prevents nuisance tripping due to rapidly fluctuating power line conditions.
This unit was designed for use in applications with fire control panels, but may be used anywhere these features are required.
