Find out what the KR XX.NN capillary thermostat has to offer

The KR XX.NN capillary thermostat is a single-pole temperature controller operating on the principle of liquid expansion, designed for temperature control in single-phase domestic and similar appliances. The device’s design is based on a switching unit and a capillary temperature sensor, ensuring stable and reliable operation in everyday applications. The switching unit performs micro-disconnection of the phase conductor, and the device is available in versions with or without alarm outputs, enabling indication of the micro-disconnection status of the electrical load. The thermostat is not intended for disconnecting electrical appliances from the mains and should be used in accordance with the ČSN EN 60335-1 standard. By using the KR XX.NN capillary thermostat, you gain:

Precise temperature control within the range of 7–95°C

Flexible installation thanks to a 500 mm or 1000 mm long capillary tube that can be bent

Workplace safety thanks to micro-disconnection of the phase conductor

Option to indicate when the load is disconnected (version with alarm outputs)

Easy to adapt to the device’s design, as the connection unit can be installed in any position

Reliable operation without consuming Electricity, plus low running and maintenance costs
