GEM1 series plastic shell type circuit breaker. Its rated insulation voltage up to 800V, suitable for AC 50Hz, rated working voltage 690V and below, rated working current up to 800A circuit for infrequent switching and infrequent starting of motor. The circuit breaker has overload, short-circuit and under-voltage protection functions, which can protect the line and power equipment from damage.
Applicable working environment:
1. Altitude of 2000m and below;
2. Surrounding medium temperature not higher than +40ºC (+45ºC for marine products) and not lower than -5ºC;
3. Able to withstand humid air;
4. Resistant to the influence of smoke and oil mist;
5. Resistant to the effects of mold and mildew;
6. Maximum inclination of ±22.5ºC;
7. can work reliably when subjected to normal vibration of the ship;
8. Can work reliably when subjected to seismic conditions (4g);
9. In the medium without explosion risk, and the medium is not enough to corrode the metal box to destroy the insulation of the gas and conductive dust;
10. In places where there is no rain or snow.
