Littelfuse SymCom 350-600 MotorSaver Protection Relay.

The MotorSaver 350-600 Protection Relay is a heavy-duty microcontroller-based voltage monitor used 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). The trip delay prevents nuisance tripping due to rapidly fluctuating power line conditions. Since the 350 series uses heavy-duty relays, it comes in fixed voltage range models rather than a dual auto-ranging version like the model 250.

Protects 3-Phase Motors From:
• Phase loss
• Phase reversal
• Low voltage
• Voltage unbalance

Standard Features:
• Bi-color LED Indicator light is green in normal conditions and red during trip conditions
• Transient protection meets IC 1000-4-5L1995 standards to handle tough conditions
• Advanced LED Diagnostics: used for troubleshooting and to determine relay status

The Model 350-600 Features:
• SPDT
• Fixed Trip Delay (Under Voltage: 4 seconds; Unbalance/Phase faults: 2 seconds)
• Fixed Restart Delay (2 seconds)
