Littelfuse 201-575-AU-OT Voltage Monitor Product Description

The Model 201-575-AU-OT is the newest, most versatile, plug-in style voltage monitor designed to protect 3-phase motors from damaging power conditions. Its wide operating range combined with UL, cUL and CE compliance enables quick access to domestic and global markets. 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 MotorSaver's output relay is deactivated after a specified trip delay.
