Capillary thermostat KR XX.NN

Description

Capillary thermostat KR is a single-pole temperature regulator based on the principle of liquid dilatation. It consists from two basic parts: switching unit and capillary temperature sensor. The switching unit ensures micro-disconnection of phase wire. Thermostat is manufactured as circuit-opening type with or without signallingterminal that can signalize micro-disconnection of electrical load. Thermostat is intended to single-phase appliances for household and similar applications the norm ČSN EN 60335-1 is valid for.

Usage for another purposes must be consulted with manufacturer. Thermostat is not intended for disconnection of electrical appliance from electrical network.

Advantages

  1. variable location of temperature sensor in relation to position of switching unit
  2. switching unit can be installed in any position
  3. capillary can be bent according to installation need
  4. no consumption of electrical power
  5. low operating and servicing costs
