Littelfuse SymCom 460-VBM MotorSaver Protection Relay.

Littelfuse SymCom 460-VBM MotorSaver is designed to protect 3-phase loads from damaging power conditions. A unique microcontroller-based voltage and phase sensing circuit constantly monitors the 3-phase voltages to detect harmful power line conditions. The output relay reactivates after line power conditions return to an acceptable level for a specified amount of time (Restart Delay). The trip and restart delays prevent nuisance tripping due to rapidly fluctuating line power conditions. The voltage monitor automatically senses whether it is connected to a 190-240VAC 60Hz system, a 440-480VAC 60Hz system or a 380- 416VAC 50Hz system. Other adjustments include a 1-500 second restart delay.

Protects 3-Phase Motors From:
• Loss of any phase
• Low voltage
• High voltage
• Voltage unbalance
• Rapid Cycling

Note: The Model 460-VBM has a fixed 6% voltage unbalance trip point and user adjustable low and high voltage trip points.
