Description

Littelfuse 460-400Hz Voltage Monitor Product Description

The Model 460-400Hz is designed to protect 3-phase, 400Hz motors from damaging power conditions. The 460s wide operating range combined with UL 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. The output relay reactivates after power line conditions return to an acceptable level for a specified amount of time (restart delay). The trip delay prevents nuisance tripping due to rapidly fluctuating power line conditions.

The Model 460-400Hz has an operating range from 190- 480V, 400Hz.
