Description
The Rheem-Ruud 42-19737-01 Sequencing Relay is an electrical control component designed for managing circuit activation in HVAC systems. Operating with a 24-volt coil and double-pole single-throw normally open configuration the relay controls power distribution between connected equipment during sequencing and operational cycling. It is commonly installed in furnaces, air handlers, and electric heating equipment where timed circuit is required for staged part operation and load management. Within the electrical assembly the sequencing relay operate as a switching interface that support controlled circuit activation, operational coordination, and stable performance.
