General
The main feature of the WKB0 control and protection switch is to achieve integrated, internally coordinated control and protection functions on a single structural product, which can replace various traditional discrete components such as circuit breakers (fuses), contactors, overloads(or overcurrents, phase failures) protective relays, starters, isolators, and motor comprehensive protectors. CPS has the function of controlling operations through both remote automatic control and local human control. It has coordinated time-current protection characteristics, has self-coordination of control and protection, and continuous operation after short circuit. It has high breaking capacity and arc flashover. It has the advantages of small distance, long life, adjustable protection setting current, easy operation, and diverse and complete supporting accessory modules. It can realize the control and protection of motor loads and power distribution loads.
The emergence of WKB0 control and protection switch fundamentally solves various problems of unreasonable control and protection coordination caused by unreasonable selection of traditional discrete components (usually circuit breakers or fuses + contactors + overload relays). In particular, it overcomes the phenomenon of incoordination between protection characteristics and control characteristics when electrical products using different assessment standards are combined together, greatly improving the operational reliability and continuous operation performance of the control and protection system.
The standards WKB0 control and protection switches comply with are IEC60947-6-2 (1997) "Low-voltage switchgear and control equipment - Part 6: Multifunctional electrical appliances Section 2: Control and protection switches" (first edition in August 1992) and GB14048.9-1998 "Low-voltage switchgear and control equipment - Multifunctional electrical appliances (equipment) Part 2: Control and protection switches (equipment)" (equivalent to IEC60947-6-2)
