TLKBO/KBO Control and Protection Switching Device

KBO products using a a modular single product structure type , and integrates traditional circuit breaker ( fuse) , thermal relays, contactors , overload ( or over-current , phase failure ) protection relays , starters, isolator the main function with remote automatic control and local direct human control panel indication and the electromechanical signal alarm function , with over- voltage protection function , with time off relative lack of protection has coordination - current protection characteristics ( three sections with inverse time , definite time and instantaneous protection features ) . Need optional function modules or accessories , control and protection of all types of motor load , the load distribution can be achieved .

 

The KBO is mainly used in AC 50Hz (60Hz ) , rated voltage up to 690V , rated current from 3A to 100A , adjustable operating current from 0.12A to 100A power system is turned on , carrying and breaking normal conditions ( including the provisions of overload conditions ) the current, and can be switched on , carrying and breaking the provisions of the non-normal conditions (e.g. , short circuit) under current.

 

 

Its structure and function , KBO products is no longer a contactor or circuit breaker , thermal relay single product , but a set of control and protection systems . It appears from the fundamental solution to the traditional discrete components (usually a circuit breaker or fuse + contactor + overload relay ) unreasonable choice , control and protection coordination unreasonable problems , especially overcome the combination between different appraisal standards of electrical products to protect and control characteristics together with the imbalance , which greatly improves the performance of the operation of the control and protection system reliability and continuous operation .

 

Field of application:

KBO has control and protection features integrated, modular , compact structure , high degree of protection of environment pollution , breaking the high short-circuit current capacity , short arcing distance , electricity and long life , complete protection function , performance and reliability in continuous operation high , the use of the installation and maintenance easy to operate a series of advantages , and therefore particularly suitable for the following systems : industrial distribution facilities in the field of metallurgy, coal, iron and steel, petrochemicals , ports , ships , railway and motor protection and control system ; motor control center ( MMC), Intelligent electronic control system , or require the rated running breaking capacity Ics of up to 80KA distribution control and protection system ; single motor control and protection systems ; distribution centers, commercial and residential facilities in a modern building lighting , power conversion , pumps , fans , air conditioning , fire protection, lighting and other electrical control and protection systems ; remote control lighting system . Hospital information processing center ( banks , municipal securities trading center , etc.) telecommunication rooms commercial buildings ( shopping malls , supermarkets , supermarkets, etc. ) Infrastructure ports or rail systems ( airports , railway passenger transportation center , etc. ) highway lighting or ventilation systems the army post control and protection system ( such as border posts, radar machine station ) fire protection system on various occasions fire pump , fan, etc.
