Description
The York S1-UMSR-50 Motor Start Relay Universal is a component-starting control part that manages electrical switching during the initial energizing stage of an element circuit. Rather than providing the motors power directly, the relay responds to the control circuit and establishes or interrupts the required starting connection within HVAC systems. Its universal 110-270V specification defines the voltage range for the relays intended electrical application. The part interfaces with the component, wiring, and related controls as part of the startup sequence. It is used in motor circuits where this specific start-relay configuration is for by the equipments electrical design.
