Circuit Shield Type 25V 424K105 Synchronism Check Relay; 10sec, 120V Measure
Overview
Description
Name: Circuit Shield Type 25V 424K105 Synchronism Check Relay
Function: Synchronism Check / Voltage Monitoring Relay
Timing: 10-second delay
Input: 120V measure
Overview:
The Circuit Shield Type 25V 424K105 is a synchronism check relay used in electrical power systems to verify that two AC voltage sources are in proper synchronism before they are connected together. It ensures that voltages, frequency, and phase angle are within acceptable limits so that parallel operation of generators or connection of loads can occur safely and without damage.
Key Features:
Designed to measure 120 V AC input for voltage comparison
