The SWOM1E series electronic plastic shell circuit breaker is suitable for infrequent switching and infrequent motor starting in circuits with an AC 50Hz (or 60Hz), a rated insulation voltage of 800V, a rated working voltage of 400V, and a rated working current of 800A. The circuit breaker has overload long delay inverse time, short circuit short delay inverse time, short circuit short delay definite time, short circuit instantaneous and undervoltage protection functions, as well as residual current protection (optional), phase loss protection function (optional), which can protect the circuit and power equipment from damage. The circuit breaker has complete and accurate protection characteristics, which can improve power supply reliability and avoid unnecessary power outages. The "Z, B" type control has a communication interface, It can be used for "four remotes" to meet the requirements of the control center and automation system.
Circuit breakers are divided into two types based on their rated limit short-circuit breaking capacity: M-type (higher breaking type) and H-type (high breaking type). This circuit breaker has the characteristics of small volume, high breaking capacity, short flashover, and vibration resistance.
The circuit breaker can be installed vertically (i.e. vertically) or horizontally (i.e. horizontally).

The intelligent controller is the core component of the molded case circuit breaker, which is used for motor protection or power distribution protection, achieving measurement, protection, control, and communication functions in one, making the circuit and power equipment vulnerable to overload, short circuit, grounding and other faults.
1. Adopting MCU microprocessor controller with stable and reliable performance: This intelligent controller can provide its own power supply. As long as one phase is powered on, it can ensure the normal operation of the protection function when the current is not less than 20% of its rated value;
2. Selective cooperation with three-stage protection: using circuit breakers of Class B and other short-circuit protection devices connected in the same circuit, it has selective cooperation under short-circuit conditions: setting protection function parameters such as overload long delay inverse time, short-circuit delay (inverse time, definite time), and short-circuit instantaneous. 3. It has three-stage protection parameter settings for action current and action time, Can be adjusted in 4 to 10 gears: Users can adjust the controller according to the load current requirements, or choose to turn off the corresponding function according to user requirements (customized function, to be specified by the user when ordering);
4. High current instantaneous tripping function: When the circuit breaker is closed and running, if it encounters a short circuit high current (≥ 20lm), the circuit breaker magnetic tripping mechanism can directly trip, making dual protection more reliable and safe;
5. Equipped with tripping test function: Input DC 12V voltage to test the action characteristics of the circuit breaker;
6. Fault self-diagnosis function: protect and detect the working status and operation of the intelligent controller itself;
7. It has pre alarm indication and overload indication: when the load current reaches or exceeds the set value, the corresponding light guide column exports the light source;
8. Dual air gap technology of magnetic flux converter: more reliable and stable operation, eliminating misoperation, reliable tripping, and small power;
9. High protection accuracy: overload protection, short circuit short delay protection action time accuracy ± 10%; short circuit instantaneous protection action value accuracy ± 15%;
