difference between molded case circuit breaker and frame circuit breaker

Introduction to the Structure Composition of Molded Case Circuit BreakerIntroduction to the Structure Composition of Molded Case Circuit Breaker

Development Trend of Molded Case Circuit Breaker IndustryWith the wider use of plastic case circuit breakers, the requirements for circuit breakers are getting higher and higher. In order to save space and achieve beautiful effect, the volume of circuit breaker is smaller and smaller, but the function is more and more powerful. Molded case circuit breaker is developing towards large current and small volume.

what is the meaning of parameters of plastic case circuit breakermolded case circuit breaker can automatically cut off the current when the current exceeds the jump setting. plastic case refers to the use of plastic insulators as the shell of the device, used to isolate between conductors and grounding metal parts. plastic case circuit breakers usually contain thermomagnetic jump-off units, while large-scale plastic case circuit breakers are equipped with solid-state jump-off sensors...

Explanation of Specification Type Meaning of Plastic Case Circuit Breaker of Hangkai Electric ApplianceHangkai Electric Appliance mainly operates two kinds of moulded case circuit breakers, HKM1 moulded case circuit breaker and HKM3 moulded case circuit breaker, the corresponding model meaning explanation.

selection and use of double power supply automatic conversion switchwhen converting power supply between city power and generator, the particularity of generator should be considered firstly. it is confirmed that generator will start automatically after city power is cut off, and can be output only after the index of generator power supply reaches stable value, and has interconnection device. select and use ats... according to conversion time.

Summary of Type Meaning of Common Circuit BreakersAt present, the model of circuit breaker in our country is generally composed of characters, symbols and figures in the following ways according to the national technical standards.

Selection Basis of Miniature Circuit Breaker and Molded Case Circuit BreakerMiniature circuit breakers and plastic case circuit breakers belong to circuit breakers, and their working principles are the same. The difference is that: 1. The installation mode of miniature circuit breaker is guideway installation, while the plastic case circuit breaker is screw installation. 2. The maximum current level of miniature circuit breaker is less than 63A, and the highest current level of plastic case circuit breaker is 2000A.

Noun Interpretation: Small Molded Case Circuit BreakerSmall plastic case circuit breaker is used in AC 50HZ, rated current to 63A, single-phase 230V and three-phase 400V circuits. It is mainly used for overload and short-circuit protection of lighting lines, as well as in normal circumstances for the less frequent conversion of lines.

Function Introduction and Type Selection Guidance of Moulded Case Circuit Breaker AccessoriesAs the derivation and supplement of circuit breaker function, the accessory of plastic case circuit breaker (hereinafter referred to as circuit breaker) adds control means and enlarges protection function for circuit breaker, making the use of circuit breaker wider, the protection function more complete, and the operation and installation mode more. Therefore, at present, the accessory of circuit breaker has become an integral part of circuit breaker.
