Littelfuse SymCom 201A-9 MotorSaver Protection Relay.

Littelfuse SymCom 201A-9 Protection Relay 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. The 201A includes advanced single LED diagnostics, where color and different light patterns distinguish between faults and normal conditions. 

This unique microcontroller-based voltage and phase-sensing device constantly monitors the 3-phase voltages to detect harmful power line conditions. When a harmful condition is detected, the 201A’s output relay is deactivated after a specified trip delay. The output relay reactivates after power line conditions return to acceptable levels for a specified restart delay time.

Note: DASH-9 feature indicates High Voltage Detect.

Features:
• Compact design for 8-pin; DIN rail or surface mount that allows flexibility in panel installation.
• Constant monitoring of single-phase, low voltage, 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, low voltage trip.
• Auto-sensing wide voltage range automatically senses system voltage between 190-480VAC.
