## Description

201A - SymCom 3-Phase Plug-In Voltage Monitor 190-480V The Model 201A Family 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 Model 201A includes advanced single LED diagnostics, where five 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 MotorSaver's output relay is deactivated after a specified trip delay. The output relay reactivates after power line conditions return to acceptable levels. Features : Low voltage trip Single-phase trip Reverse-phase trip Fixed 6% voltage unbalance trip Single LED diagnostics Optional high voltage trip 8-pin plug-in; DIN rail or surface mount Separate indicators for: Power-up restart delay Reverse-phase trip Good voltage/relay energized Unbalance/single-phase trip High/low voltage trip Auxiliary Products: 8-pin octal socket: P/N: CT0T08-PC

Review: awesome product - fast shipping correct part
Review: good quality! - We use this in our well field which supplies water to our town. Stops repair problems due to over/under voltage, single phasing. Just a great unit! Cheap insurance!!
