Littelfuse 250A-MET LFSE 250A-MET MODEL 250A/ RIGHT FOR

Product Description

The Littelfuse 250A-MET is a microcontroller-based voltage and phase-sensing device designed for constant monitoring of three-phase voltages. This device detects harmful power line conditions and deactivates its output relay after a specified trip delay when such conditions arise. Once the voltage and phase return to acceptable levels, the relay reactivates. This model includes single LED diagnostics that provide five distinct light patterns, allowing users to easily identify faults versus normal operation.

• Microcontroller-based for precise monitoring
• Detects harmful power conditions effectively
• Includes advanced diagnostics with LED indicators

Product Highlights

Reliable performance for monitoring voltage and phase in three-phase systems. Ideal for electrical installations where monitoring power quality is essential.
