KBO switch which parameters, country hair electrical switch factory to provide you with the following confidence, www.jiandq.com 15957745520
One, product description:
( KB0N ) reversible type control and protection switch
With (KB0 ) as the main switch, and a mechanical interlock and electrical interlocking attachment assembly, constitute a reversible control and protective switching devices ( KB0N CPSN ), applicable to the motor of reversible or two-way control and protection.
CPS ( KBO ) series of products, the circuit breaker contactor, overload relays, isolating switch and the separation of components of the main function integration, and can realize multiple signal, control and protection in the product from the. Has the advantages of small volume, short circuit breaking performance index is high, and long service life and high reliability, safe and convenient use, energy saving and material saving, the main performance indicators have reached the international leading level.
( KBOD ) double speed type control and protection switch
With (KB0 ) as the main switch, and the contactor, electrical interlocking attachment assembly, consisting of two speed motor controller CPSD ( KB0D ), suitable for double speed motor control and protection.
Double speed motor controller is configured with three:
The configuration of a: high-speed fire type ( overload, overcurrent alarm only not trip ), low speed as the basic type;
The configuration of two: high, low speed are the basic type;
The configuration of three: high, low speed are fire type ( should be marked with special orders ).
In two, and other products:
With the separation of electrical system in
A. With control and protection from common characteristic
CPS ( KB0 ) series control and protective switching devices with control and protection functions, equivalent circuit breaker ( fuse ) + + + auxiliary electrical overload relay contactor. Very good solution to the separation element cannot or difficult to solve element between the protection and control characteristics matching problem, so that the protection and control characteristics with more perfect and reasonable ( with inverse time limit, and the instantaneous protection characteristic of three segments ), as long as the load power or current can be properly selected a single product, instead of including self power incoming line end to the load end of various electrical appliances, without lowering the capacity; greatly reduces the workload of design.
There is nothing comparable to this B. With the operation reliability and continuous system operation performance
CPS ( KB0 ) in breaking short circuit current without maintenance can be put into use, that is breaking short circuit faults of continuous running performance: CPS ( IKB0 ) in the breaking short-circuit current after the test, is not less than 1500 AC-44 electric service life, which is composed of circuit breakers and other separation components the system is difficult to achieve, CPS ( IKB0 ) of this feature of the system is greatly improved the reliability of operation and continuous operation of the system, the Ics 80kA index is similar products in the leading international, domestic highest index.
C. Saving energy and material
CPS ( KB0 ) has the advantages of small volume, small installation area, without a separate component contacts, reduce line heating, energy saving, material saving etc..
Compared with the molded case circuit breaker
A. With high breaking capacity, arcing distance short of the characteristics
CPS ( KB0 ) in 380V rated short-circuit breaking capacity ( Ics Oco-co ) reached high breaking type 80kA, type 50kA, type of economic standard for 35kA, 50kA expected in short circuit current breaking time is 2 ~ 3MS, limiting factor reached 0.2 the following, reaching the leading level of molded case circuit breakers, to fuse current limit level, greatly limiting the short-circuit current of the system dynamic, thermal shock. CPS ( IKBO ) arcing distance of only 20 ~ 30mm.
B. And molded case circuit breaker. Compared with protection system, protection setting current can be adjusted characteristics
CPS ( KBO ) of the current can be adjusted in the panel, which in addition to the conventional protection under the current load power setting, overcurrent protection setting current in adjusting the current value at the same time adjustment ( distribution load adjustment range is 3 ~ 6Ie, motor load adjustment range of 6 ~ 14Ie ). To overcome the molded case circuit breaker with short circuit protection setting current manufactured after the user can adjust the shortcomings, such that CPS ( KB0 ) products even mounted at the ends of the line, short-circuit current is small, but also has a very good short circuit protection function.
And the contactor performance compared with long service life, convenient operation characteristics
Manual operation, but also can realize the automatic remote control function. Using advanced contact and electromagnetic system separation design, effective suppression of contact bounce two times, greatly improving the product life, and is especially suitable for heavy load starting the harsh situation.
