CPS or “starter-controllers” are designed to fulfil control and protection functions simultaneously (overload and short-circuit). In addition, they are designed to carry out control operations in the event of short-circuit. They can also assure additional functions such as insulation, thereby totally fulfilling the function of “motor starter unit”. They comply with standard IEC 60947-6-2, which notably defines the assigned values and utilisation categories of a CPS, as do standards IEC 60947-1 and 60947-4-1.The functions performed by a CPS are combined and coordinated in such a way as to allow for uptime at all currents up to the Ics working short circuit breaking capacity of the CPS. The CPS may or may not consist of one device, but its characteristics are assigned as for a single device. Furthermore, the guarantee of “total” coordination of all the functions ensures the user has a simple choice with optimal protection which is easy to implement.

The CPS series control and protective switching device characteristics are integrated, internal coordination of control and protection features in a single structure in the form of products, can replace the circuit breaker (fuse), contactors, overload (or over-current, off phase) protection relays, starters, isolator, motor comprehensive protection variety of traditional separate
components. CPS with remote automatic control and local human control types, coordination time - current protection characteristics, has the control and protection self-match, continuous operation after short-circuit, high breaking capacity, arcing small distance, long life, protection current adjusted characteristics, easy to operate, supporting complete diverse and accessory module, etc., achieve to control motor load and distribution load.

CPS series control and protection electrical switches device solve the traditional question that control and protection coordinate unreasonable (usually cause by a circuit breaker or fuse + contactor + overload relay), especially to overcome the imbalance of different standard electric equipments combined, greatly improve reliability continuous control and protection system performance.

The first generation of the CPS series control and protective switching devices has large size and use bimetal technology. The second generation product just solve the problem of large volume, but no more big breakthrough in technology. Targeting this opportunity with the widening and deepening microelectronics technology in the lowvoltage electrical products industry, our company based on the latest microelectronic technology, go high-end product design road, based on KBO products, investment to develop international advanced product CPS/KB0 series control and protective switching devices, which overcome disadvantages of KBO products, collect the advantages of low-voltage apparatus discrete components, full-featured, reliable
performance, simplify and optimization the system for low-voltage distribution and control.
