Danfoss KPS81 060L311066 TERMOSTAT

Danfoss KPS81 060L311066 Thermostat is a heavy-duty limit thermostat designed to provide temperature control within a range of 60–150 °C. With its SPDT gold contact configuration and automatic reset function, it ensures system safety during overheating conditions. Thanks to its IP67 protection class, it is resistant to moisture, dust, and water splashes. The rigid sensor and metal cable gland allow for easy installation. The thermostat can be used in applications where the bulb temperature reaches up to 250 °C, and the temperature differential can be adjusted by the user between ≈ 5–25 °C. It is ideal for use in marine applications, boiler systems, industrial furnaces, and cargo vessels, where high temperatures and harsh environmental conditions are present.
