Overview
The “Auxiliary undervoltage” element monitors undervoltage conditions of the auxiliary voltage. It resets instantaneously. The minimum voltage setting selects the operating voltage below which the element is blocked.
For more detailed information on “Auxiliary undervoltage” element, refer to GE, Universal Relay (UR) family of products, Version 8.0x manuals.
