Description
The Lennox 10M51 MR is a high-pressure switch specially made for Lennox HVAC equipment, such as air conditioners and furnaces. It serves as a safety guard since it measures pressure within the system. At a preset pressure of 450 PSI, the switch gives an electrical signal. In case the pressure rises to a certain level, the switch switches off the power to the compressor to avoid subsequent harm. On the other hand, if the pressure is too low the contacts make to close the circuit to restart the compressor for proper system functioning. the Lennox 10M51 MR protects your HVAC equipment by maintaining the right pressure.
