SymCom 355-400 MotorSaver
SymCom 355-400 - In Stock
3-phase voltage monitor is perfect for heavy-duty applications that need both protection and diagnostics while the motor is shut down. Applications include rural pump panels, commercial HVAC equipment, oil rigs, and rural HVAC equipment. The Model 355-400 monitors 380 to 480V input voltages.
In Stock. Unique microcontroller-based voltage and phase-sensing circuit constantly monitors the 3-phase voltage to detect harmful power line conditions such as single-phasing, high voltage, low voltage, phase reversal, voltage unbalance, and high voltage (optional). 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). The trip delay prevents nuisance tripping due to rapidly fluctuating power line conditions.
