Description
The Trane COL03779 Holding Coil AMG is an electromagnetic control component designed to maintain the energized position of a contactor or relay during equipment operation. When supplied with 24-volt power at 50/60 Hz, the coil generates a magnetic field that holds the associated contacts in place, allowing electrical circuits to remain engaged as required. It is fitted within the control assembly where it interfaces with the contactor or relay mechanism. Stable magnetic actuation supports accurate electrical control, support to prevent unintended circuit interruption, and contributes to coordinated operation of connected system components in HVAC systems.
