Technical data, application and settings of the SMR1e release of the Record Plus FK800 selective circuit breaker for rated current 800A manufactured by General Electric
Application of selective circuit breaker Record Plus 800A
The switching device of the FK800 Normal subtype performs the following functions:
- forced switching on and off of the protected three-phase circuit;
- separating the contacts, ensures the isolation distance;
- protects the electrical network from short circuit currents (abbreviation short circuit) and overloads;
- provides selectivity (application category B or fixed time delay in the short circuit zone) to downstream protection devices;
- effective extinguishing of the electric arc;
- long-term transmission of rated electric current during normal operation.
It is installed in switchgears of industrial, office buildings and structures, as an introductory machine.
Fulfills all the requirements of the international standard IEC 60947.2 (the original translation is given in the regulatory document GOST 50030.2 ).

SMR1e electronic release settings
Adjustments of the electronic trip unit can take into account the specific requirements of the user and provide the correct operation of the circuit breaker.
Overload protection can be set from 320 to 800 amps (8 positions total from 0.4 to 1 In). In this case, the release trips with a delay of 5 seconds at 7.2 In.The device has three LEDs:
Overload protection can be set from 320 to 800 amps (8 positions total from 0.4 to 1 In). In this case, the release trips with a delay of 5 seconds at 7.2 In.The device has three LEDs:
- power supply and operation of the release is normal (green);
- overload indication (at 1.05 In the yellow LED is constantly on);
- the product is not operational (red LED).
