Structural Profile

·Fixed circuit breaker mainly consists of contact system, intelligent controller, manual operation mechanism, electric operation mechanism and mounting plate.

·Drawer type circuit breaker mainly consists of contact system, intelligent controller, manual operation mechanism, electric operation mechanism and drawer seat.

·The circuit breaker is in the form of three-dimensional arrangement, featuring compact structure and small size. The contact system is enclosed in the insulated base plate, and each phase of its contacts forms a small chamber. The intelligent controller, manual operating mechanism and electric operating mechanism are sequentially arranged in front of it to form independent units, which is convenient for maintenance and repair.



Performances

·Intelligent disconnectors are divided into: L-type (economic), H-type (standard), and H-type (communication).

·It has four protection features, such as overload long delay inverse time, short-circuit instantaneous protection, and asymmetrical grounding (zeroing) fault protection.

·Display function: display the working current of the circuit breaker, display various protection status.



Normal Operating Condition

·Ambient air temperature: the upper limit value does not exceed +40°C, the lower limit value does not fall below -5°C, and the average value for 24h does not exceed +35°C.

·Atmospheric conditions: Atmospheric relative humidity does not exceed 500h at an ambient air temperature of +4°C. Higher relative humidity is possible at lower temperatures, with a monthly average maximum relative humidity of 90°C in a wet month, together with an average minimum temperature of +25°C in that month, taking into account the condensation that occurs on the surface of the product as a result of the temperature change.
