Temperature Monitoring Relay
UKT-01
Temperature monitoring relay UKT-01 provides control of an emergence of the out-of-specification temperature modes ( up to 5 control points) and is used for equipment protection because of an excessive overheat.
Application
The device is intended for:
- measurement and control of temperature of electrical machines, including coils (indirectly through enclosure temperature), bearings and other parts of the electric motor;
- to avoid an excessive temperature growth and an emergence of the out-of-specification temperature modes;
- to give a warning signal about excess of the established temperature of heating of the electric motor controlled parts;
- to disconnect switch control apparatus by breaking of a circuit of load control (switching of electrical alternating current circuits) in case ofan excessive temperature growth;
- indication of the temperature current value of the channel (for choice).
