Description

The Bohn 5709L Refrigerator Defrost Thermostat 3-Wire Surface Mount 120/240V, 25 Amp is a control component, used to regulate defrost cycle operation in commercial refrigeration systems. It operates by sensing evaporator surface temperature and automatically opening the electrical circuit at 55°F while closing it again at 35°F, controlling power flow to defrost heaters based on temperature conditions within the unit. The internal switching mechanism to the thermal changes through a calibrated sensing element that activates or interrupts the connected circuit during refrigeration, and defrost sequences. It is typically mounted directly onto the evaporator coil or nearby tubing inside compatible refrigeration equipment.
