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.
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.
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.
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.
How to choose plastic case circuit breaker?With the increasing popularity of plastic case circuit breaker, it involves various fields, even at home. The use of plastic case circuit breakers is even related to people's life safety. They can not be purchased and used at will, nor can they be thrown away directly after they are not like other commodities. Once the quality of plastic case circuit breaker is not up to standard, it will cause serious consequences. ...
How to Select Molded Case Circuit BreakerThe selection of molded case circuit breaker can be divided into two aspects: parameter selection and type selection. Parameter selection includes: voltage, current, frequency, mechanical load, dynamic and thermal stable current and duration, voltage withstanding capacity, operation performance, environmental conditions, etc.
