Description
The York S1-02435341000 3-Phase Time Delay Relay is an essential component in HVAC systems and its purpose is to add a precise delay in the starting sequence of three-phase motors. This delay is necessary to avoid a high surge current at the time of motor start which is not only harmful to the motor and the electrical supply system but is also costly in terms of energy consumption. The relay works by measuring a voltage across all phases of the motor and then introducing a certain amount of time before the motor begins to run. This method of gradual or staggered starting safeguards the motor against damage, and lowers the load placed on the electrical network and on the whole system.
