KNL5-63 Residual Current Circuit Breaker(without over-current protection) It is applicable to industrial sites, commercial sites, tall buildings, and civil houses. When there is human electricity shock or if the leakage current of the line exceeds the prescribed value, it will cut off the power rapidly to protect human safety and prevent the accident due to the current leakage. lt can be used as an infrequent changeover of the line in a normal situation. lt complies with the standard of GB16916.1 and IEC/EN61008.1.

KNB1-63 series Miniature Circuit Breaker Installed with standard din rail it is convenient and easy in usage. It is mainly used in the line of AC 50/60Hz rated working voltage to 240V/415V, and rated current to 63Aas protection against overload and short-circuit.itcan be used as infrequent-and-off operation and changeover.

KNM2 Moulded Case Circuit Breaker It is used to distribute electric power and protect the line and power apparatus from being overload and short-circuit protection of the motor, and can be installed vertically and horizontally.

Moulded Case Circuit Breaker MCCB 3p (KNM3 Series MODIFIED TYPE) with Ce CB160A/250A The rated insulation voltage of this circuit breaker is 750V which is applicable for the electricity distribution network of AC50Hz, rated working voltage 690V and below, rated working current from 6A to 1600A. It is used to distribute electric power and protect the line and power apparatus from being overload and short-circuit protection of the motor. Can be installed vertically and horizontally.

The Canton Fair is a trade fair held in the spring and autumn seasons each year in Canton (Guangzhou), China. Its full name since 2007 has been China Import and Export Fair, renamed from Chinese Export Commodities Fair, also knows as The Canton Fair. The Canton Fair is the largest trade fair in China. It has the largest assortment of products, the largest attendance, and the largest number of business deals made at the fair. The 123rd session of China Import and Export Fair will be held on 15th, April 2018 at the Canton Fair Comlex. KORLEN as an exhibitor,we sincerely invite you to visit our booth, and provide more information about what we produce, what we sell. The details are listed as below: Date: Apr 15, 2018 -- Apr 19, 2018 Location: Canton Exhibition Centre, China Stand: 10.3C31 - 32D13 - 14

Most people do know what miniature circuit breaker is, but they may not know how miniature circuit breaker works, and how they protects from short circuit and overload, as they don`t know miniature circuit breaker construction, which is exactly the basic for knowing more about miniature circuit breaker. Here we analyse the construction with example of mcb circuit breaker , which is mainly composed of parts as below: (1) Operating handle: for circuit breaker`s switching, closing and resetting manually, also for locally instructing circuit breaker`s state of switching and closing (2) Tripping mechanism (including lock catch, lever and tripping panel): for connecting and separating from contact (3) Wiring terminals: for wiring at top and bottom (4) Device for contact (including moving and static contacts and joint plate): for current switched on and cut off (5) Bimetal strips: bimetal strips bend as two bimetal strips have different coefficients of thermal expansion, the bending angle increases as overload current rises, which makes bimetal strips touch lever and then push tripping mechanism, thus making miniature circuit breaker play the role of overload protection (6) Eletromagnetic solenoid (also called as instantaneous coil): when short-circuit happens, large current goes through induction coil, which will cause a strong suction and then push lever, making circuit breaker trips fast (7) Adjusting screw: for factory workers to adjust tightness of bimetal strips, thus realizing adjustment of tripping current value of overload (8) Arc-suppression device (including arc extinguish chamber and run-on plate): for arc suppressing (9) Circuit breaker case, including base and cover Items above are the main parts for a MCB. After you really know these main parts and their functions, you will naturally understand how a miniature circuit breaker works!

Use this way to make could be by switching to LED lights in lieu of your regular lighting. That`s steady (so far) rather than uniform lighting. Actually from LED light of development for people has been concern it for using our life. LED lights are energy efficient and offer you all the luminosity, you require with minimal damage to the environment. But growth in the lighting market has in fact varied, with packaged LED growth in overall lighting growing from 2006 to 2011 between 25% and 65% a year but never doubling or tripling in one year. There's certainly been no tipping point for LED lighting.LED network of excellence than conventional lamps, PCB is LED powered carrier, also led the heat carrier, so the heat sink thermal and printed circuit board design is very important. It's only fair that you do you sit by adopting certain pro-green measures for your lifestyle. In a world most are where concerns about the environment are increasingly taking up the centre stage. If just depends on using low heat resistance of LED components is failed to for lamps device construction capable of thermal system, and most applicable to reduces from PN node to around environment of host resistance. However, different applications advance at different times. Use LED lights are a way of our life.

With the circuit breaker is becoming increasingly popular, many industries can use the family can also be used. But the Moulde Case Circuit Breakers relates to personal safety, can`t casually buy. If the quality of circuit breaker does not pass, will have very serious consequences. What MCCB You should buy ? The industry believes that consumers should buy a certification standard machine. For example, with the IEC flag and China low-voltage electrical appliances GB standards, these are the most basic. Want to buy MCCB quality, you have to check it is not described above. If all certified certification standards are quality and safety performance is qualified. Next, consumers need to choose according to the specific use of the environment here. If the rated current under 630A, the current is not large short circuit breaker, can choose the plastic case. If the rated current is large, so the best choice of circuit breaker frame. If the branch short-circuit current, you have to consider other factors. But there is one point to note is that circuit breaker must have leakage protection measures, otherwise can not buy. When all the factors are considered finished, must consider the price of MCCB MCCB. Different brands, the price is not the same. So consumers want to buy cost-effective products, it is better than three, look at the most affordable price, MCCB which of the highest quality. After these basic requirements are satisfied, you have to consider the extension of a MCCB. KNM1 series Moulded Case Circuit Breaker comply with demands of following standards:1IEC60947-1 and GB/T14048.1-2000 general2IEC60947-2 and GB/T14048.1-2001 low voltage breakers3IEC60947-4-1 and GB/T14048.4-2003 mechanical contactors and motor starters4IEC60947-5-1 and GB/T14048.5-2001 electrical equipments of electromechanical control circuit. It also has disconnecting and creepage protection function.
