Sphere of application
KNR1(LR2-D)series thermal relay can be used in the circuit of 50Hz or 60Hz, rated insulation voltage 660V, rated current 0.1-93A for protecting the phase break when the electric motor is overload.
The relay has different mechanism and temperature compensation& can be pluged in KNC1 series AC contact.
A. Fundamental parameter of the main circuit
Rated insulation voltage 660V;
Rated working current 25, 36, 93A separately;
The regulator seal of rate setting current and setting.
Current of the thermal component
B. Auxiliary circuit
There is a pair of NO and NC contact with electric insulation;
Rated insulation voltage 500V;
Rated frequency 50-60Hz;
Use group, rated working voltage, appoint thermal current and rated current.
