A higher voltage rating provides a larger safety margin against voltage spikes

preventing potential equipment damage or hazardous operation

it provides precise feedback on the contactor's mechanical state

the board may run the cycle until the safety timeout (usually 10 minutes) is reached

Rheem-Ruud 42-22655-02 Relay A higher voltage rating providesThe Rheem Ruud 42 22655 02 Relay is a professional grade Delay On Break (DOB) timer engineered for high cycle HVAC performance. This specific OEM HVAC replacement part is critical for preventing compressor short cycling, which protects the system from premature mechanical wear and electrical stress during rapid thermostat fluctuations or brownouts. Formulated as a 5 minute time delay relay, it ensures the refrigerant pressures in the compressor have
