Specializing in the production of KBO control and protection switch Tel :0577 -62,906,628 Fax 577 -62767956 Mobile: 18,205,877,547 QQ: 491 115 852 Product Overview: Series control and protection of electrical switches (hereinafter referred to KBO) mainly used in AC 50Hz (60Hz), rated voltage up to 690V, rated current from 3A to 100A, adjustable current from 0.12A to 100A power system is turned on, carrying and breaking normal conditions (including the provisions of overload conditions) under the current, and the ability to access, carrying and breaking current under a predetermined abnormal conditions (such as a short circuit). Its structure and function, KBO series contactors, circuit breakers, or thermal relay single product, but a set of control and protection system. It appears from the fundamental solution to the traditional use discrete components (usually a circuit breaker or fuse + contactor + overload relay) unreasonable choice, control and protection with the unreasonable, especially to overcome the combined, protection and control characteristics with an imbalance between the different assessment standards of electrical products, which greatly improves the performance of the control and protection system reliability and continuous operation. [Application:] KBO control and protection features integrated, modular, compact structure, high degree of protection of environmental pollution, high short circuit current breaking capacity, short arcing distance, power, long life, protection functions, continuous operating performance and high reliability, installation and maintenance operations and a series of advantages, especially suitable for the following systems: industrial facilities in the field of metallurgy, coal, iron and steel, petrochemical, ports, ships, railway power distribution and motor protection and control system ; motor control center (MMC), intelligent electronic control system or rated to run breaking capacity Ics up a 80KA distribution control and protection system; single motor control and protection systems; distribution center commercial and civilian facilities modern architecture lighting, power conversion, pumps, fans, air conditioning, fire protection, lighting and other electrical control and protection system; remote control lighting system. Highway lighting or ventilation system of the hospital information processing center (banks, municipal securities trading center, etc.) telecommunication rooms commercial buildings (shopping malls, supermarkets, supermarket, etc.) infrastructure ports or rail systems (airports, railway passenger transport center) station control and protection system (such as border posts, radar stations) fire protection system for all occasions fire pumps, fans and other ■ advantage ■ separation of electrical system compared to a control and protection from the characteristics of Q-KB0 series of control and protection of electrical switches set control and protection functions into one, the equivalent of the circuit breaker (fuse) + contactor + overload relay auxiliary appliances. with unparalleled reliability and continuous operation of the system performance Q-KB0 without breaking short-circuit current maintenance can be put into use, that continuous operation of a short circuit breaking performance. ■ Compared with MCCB has high breaking capacity, short arcing distance of the characteristics of molded case circuit breaker protection system, compared with a protection setting current can be adjusted to the characteristics of HKCPS the-KB0 the mechanical life of 500 to 10 million times , electrical life AC-43 for 100 to 120 million times, both local manual operation, while achieving automatic control functions. Advanced contact with the magnetic separation system design, effectively inhibited the secondary contact bounce, greatly improving the electrical life, and especially suitable for heavy-duty starting and other harsh applications. Field of application due HKCPS-KB0, control and protection features integrated, modular, smaller structure, high degree of protection of environmental pollution, high short circuit current breaking capacity, short arcing distance, power, long life, protection functions, continuous running performance and high reliability, easy installation and maintenance operations and a series of advantages, especially applicable to the following system ■ industrial facilities the △ metallurgy, coal, iron and steel, petrochemical, ports, ships, railway and other areas of power distribution and motor protection and control system ; delta motor control center (MMC), intelligent electronic control system or rated to run breaking capacity Ics up to the a 80KA distribution control and protection systems; the △ single motor control and protection systems; the △ distribution center ■ commercial and civilian facilities △ modern building lighting, power conversion, pumps, fans, air conditioning, fire protection, lighting and other electrical control and protection system; △ remote control lighting system.
