Littelfuse SymCom 102A-9 MotorSaver Protection Relay.

Littelfuse SymCom 102A-9 MotorSaver is a 3-phase, auto-ranging, dual-range voltage monitor that protects 190-480VAC, 50/60Hz motors regardless of size. The product provides a user selectable nominal voltage setpoint and the voltage monitor automatically selects between the 200V and 400V range. A unique microcontroller-based voltage and phase-sensing circuit constantly monitors the 3-phase voltages to detect harmful power line conditions. When a harmful condition is detected, the output relay is deactivated after a specified trip delay. The output relay reactivates after power line conditions return to acceptable levels.

Features:
• Automatically senses system voltage between 190-480VAC.
• Constant monitoring of single-phase, low voltage, high voltage (102A-9), voltage unbalance, phase reversal, and harmful power line conditions.
• Advanced LED diagnostics: Quick visual indicator for cause of trip. LED indications include: normal operation, power-up restart delay, reserve-phase trip, unbalance/single-phase trip, high or low voltage trip.

Note: DASH-9 feature indicates High Voltage Detect. High Voltage Trip is 110% of setpoint, Reset is 107% of setpoint.
