Description
The Rheem-Ruud 42-18287-12 Relay Coil is an essential part of the HVAC systems which ensures a reliable electrical switching and control. This relay coil is of 24 VAC with a maximum current of 12 amps. It has a double-pole double-throw contact arrangement, it is used to switch ON or OFF two different circuits or two different electrical appliances by one relay. This relay coil employs the use of an electromagnetic field to move electrical contacts from one position to another. When energized it opens or closes the connections allowing or denying electrical passage to parts of the HVAC system. It is often employed for controlling such high-current equipment as compressor, fan and heating elements. The relay enables a fine change-over and the control coil increases the effectiveness and dependability of HVAC systems.
