Service environment
. Ambient temperature: -40 ºC ~ +50 ºC .
. Daily average ambient air relative humidity ≤ 95%, on average ≤ 90%;
. Wind pressure: less than 700pa.
. Altitude: less than 3000m. . Earthquake intensity: not more than 9 degrees.
. Air Contamination: grade.
Operation Mechanism After the circuit breaker is closed, the close and open springs store energy. The inner and outer crutch arms withstand a counter-clockwise moment. Once the opening winding is electrified, the lock releases, rotating counter-clockwise, driven by the open spring, causing the inner crutch arm to open the circuit breaker. This moment remains secured by the engine, maintaining an opening state.
In the spring mechanism, upon opening, the close spring stores energy. The ratchet wheel axis withstands a counter-clockwise moment from the opening spring. This moment is secured by the holding and opening engines. Upon electrification of the opening winding, the cam and ratchet wheel release. Driven by the close spring counter-clockwise, the cam depresses the open spring to open the circuit breaker. As the circuit breaker concludes closing, the close spring releases, connecting the pawl axis with the motor via a gear. The motor activates instantly, storing energy in the open spring.
