high voltage circuit breaker,
motorized circuit breaker
1. Main functions and features
The intelligent controller is the core component of the molded case circuit breaker. It is applied to motor protection or distribution protection to realize the functions of measurement, protection, control and communication, so that the line and power supply equipment are protected from overload, short circuit and grounding.
With MCU microprocessor control, the performance is stable and reliable: the intelligent controller can supply power automatically, as long as one phase is energized, when the current is not lower than 20% of its rated value, the protection function can be guaranteed to work normally.
Selective fit with three-stage protection: use circuit breakers of category B and other short-circuit protection devices connected in the same circuit with selective coordination under short-circuit conditions: overload long delay inverse time limit, short circuit delay, short circuit transient, etc. Setting of protection function parameters
It has three sets of protection parameters for action current and action time. 4-10 steps can be adjusted: the user can adjust the settings according to the load current requirements, or select the function according to the user's requirements to turn off the corresponding function (customized function. Note when the user orders);
High-current instantaneous tripping function: When the circuit breaker is closed or during operation, if short-circuit high current (> 20 [nm) is encountered, the magnetic tripping mechanism of the circuit breaker can be tripped directly, and the double protection is more reliable and safe;
With trip test (test) function: input DC DC12V voltage test circuit breaker action characteristics;
Fault self-diagnosis function: protect and check the working status and running quiet condition of the intelligent controller itself;
High protection tip: overload protection, short-circuit short-delay protection action time accuracy t 10%; short-circuit instantaneous protection action value tip is 15% depending on the action current:
