Littelfuse 102A2 Voltage Monitor Relay 190-480V/3PH

The Littelfuse 102A2 Voltage Monitor is a precise part that can be used in 3-phase systems with a voltage range of 190 to 480 VAC. It employs a microcontroller and constantly checks voltage levels to determine situations of the voltage swell, over-voltage, and under-voltage. This monitor is especially beneficial in preventing and Provideing equipment functionality in HVAC systems like fan motors, air conditioners, and compressors. This has the advantage of automatic voltage sensing, adjustable restart delays of 2-300 seconds and LED diagnostics for pronto fault finding.
