Miniature circuit breakers are different from ordinary Miniature circuit breakers. Its advantages are small size, easy operation and many types and categories. For everyone, it can provide a variety of personalized options to achieve the desired effect. However, this must also be based at an early stage on knowledge of the basic sector in order to ensure adequate experience. Today I introduce you to the Miniature circuit breaker.
What should we pay attention to when choosing a Miniature circuit breaker?
What is the production-related significance of Miniature circuit breakers?
How can we judge whether we should choose a Molded case circuit breaker or a Miniature circuit breaker based on operation and service life?
1) The selection of Miniature circuit breakers for power distribution shall take into account the short-term delayed short-circuit on-off capability and the coordination between the delay protection levels;
2) The rated voltage of the undervoltage trigger of the Miniature circuit breaker is equal to the rated voltage of the line;
3) Selective interaction of Miniature circuit breakers and Miniature circuit breakers, Miniature circuit breakers and fuses should also be considered when selecting Miniature circuit breakers.
4)When used for motor protection, the selection of Miniature circuit breaker should take into account the start-up current of the motor and ensure that it does not operate within the start-up time.
Miniature circuit breakers refer to protective devices installed in final distribution lines and are mainly used for overload and short circuit protection of cables and electrical equipment. In a situation where the demand for electricity for national production and subsistence continues to increase and society places higher demands on the security and reliability of electricity supply, it is necessary to optimize the operational impact of the distribution network. To achieve this goal, it is necessary to install the Miniature circuit breaker scientifically and reasonably on the interrupted distribution line, to effectively protect the line and electrical equipment, to avoid overload operation, which leads to a certain safety of the cable and electrical equipment. Damage. From this point of view, Miniature circuit breakers have a high application value, and it makes sense to actively research and develop Miniature circuit breakers.
Operation and life operation see. The Molded case circuit breaker uses two sets of devices to protect against overcurrent or overcurrent. Short circuit, and the action value of overcurrent protection can be set manually, which is convenient and fast. The Miniature circuit breaker shares a number of over current and short circuit devices, and the current is not adjustable, which means that in many cases the problem cannot be solved. Molded case circuit breakers have large phase spacing and arc extinguishing covers, which have strong arc extinguishing ability, can withstand larger short circuit currents, and cannot easily cause phase short circuits, so their service life is longer than Miniature circuit breakers. Molded case circuit breakers are more pronounced in terms of flexibility in application and better in terms of adjustment flexibility than Miniature circuit breakers. The overcurrent and short circuit protection devices of the Molded case circuit breaker are independent of each other, and the trigger value of the overcurrent protection used can also be flexibly adjusted. The overcurrent protection and short circuit protection of the miniature power switch are standardized devices, and there are certain shortcomings in the adaptation flexibility.
