Overview
KB0 namely "Control and protection of electrical switches CPS" is a new type of low-voltage electrical products, is the latest development of the nineties to fill the gaps of the first generation of categories of products, as a new category of products, its product category, code-named " KB0 ", the English" Confrol and Protective Switching Device "acronym, it meets the standards IEC60947-6-2 (1997)" Low-voltage switchgear and control equipment Part 6: Multiple function equipment Section 2: Control and protective switching Electric CPS "(1992 年 8 first edition) and GB14048.9-1998" low-voltage switchgear and control equipment multifunction devices (or equipment) - Part 2: Control and protective switching CPS (device) "(identical with IEC60947- 6-2).
IEC standards and national standards for electrical codes and symbols as shown on the left.
KB0 (KBO) control and protection of electrical switches The main feature of CPS is to achieve a single structure in the form of product integration, the internal coordination of control and protection functions. Can replace the circuit breaker (fuse), contactors, overload (or over-current, phase) protection relays, starters, isolators, motor integrated protection, and other conventional separation components. KB0 with remote automatic control and in situ control of both human way control operation function, with coordination of the time - current protection special l Health, control and protection from the match, continuous operation after a short circuit. Having a high breaking capacity, small arcing distance, long life, with the protection setting current can be adjusted characteristics. Easy to operate, supporting diverse accessory module is complete, etc., can be achieved on the motor load, the load distribution control and protection.
KB0 (KBO) control and protection of electrical switches CPS appears from the fundamental solution to the traditional use of discrete components (usually a circuit breaker or fuse + contactor + overload relay) control and protection due to the choice of cooperation not cause unreasonable reasonable problems, especially to overcome due to the combined, protection features and control features with an imbalance between different assessment criteria electrical products, greatly enhancing the operational reliability of the control and protection system and continuous operation performance.
KB0 (KBO) control and protection of electrical switches CPS relatively large size of the first generation of products, the protection of the bimetal technology adoption. Although second-generation products to solve the problem of large volume. But no major protection technology breakthrough. As microelectronics technology applications in low-voltage electrical industry expanded and deepened, the company targeting this opportunity, with the latest microelectronic technology, take the road of high-end product design, based on KB0 products, has invested heavily in development of the international advanced level products TXKB0 (KBO) control and protection of electrical switches CPS. To overcome the shortcomings KB0 series, brings together the advantages of low-voltage electrical discrete components, full-featured, reliable performance. In order to simplify and optimize the low-voltage power distribution and control system provides a foundation member. TXKB0 (KBO) control and protection of electrical switches CPS is the best upgrade KB0 replacement.
