Littelfuse 460575 Voltage Monitoring Relay
The 460 series is a reliable 3-phase voltage monitor designed for protecting motors operating across 190-480VAC or 475-600VAC at 50/60Hz. It features automatic line voltage sensing, adjustable trip delays (1-30 seconds), restart delays (1-500 seconds), and a voltage unbalance trip point of 2-8%. Equipped with dual sets of contacts (Form A and B), it effectively trips under low, high, unbalanced voltages, or single-phase faults, providing enhanced motor protection. The microcontroller-based device ensures accurate monitoring, quick visual indicators, and prevents nuisance tripping with adjustable delays, making it ideal for industrial motor applications.
