Integrated controller KBO

The KB0 product adopts a modular single product structure and integrates the main functions of traditional circuit breakers (fuse), thermal relay, contactor, overload (or overcurrent, phase failure) protection relay, starter, isolator, etc., It has long-distance automatic control and local direct human control functions, panel indication and electromechanical signal alarm functions, over-voltage and under-voltage protection functions, phase and phase loss protection functions, and coordinated time-current protection characteristics (with reverse Time limit, definite time limit and instantaneous three-stage protection characteristics). The function modules or accessories can be selected as needed to realize the control and protection of various motor loads and distribution loads.

KB0 is mainly used for connecting, carrying and breaking normal conditions (including specified overload conditions) in power systems with AC 50Hz (60Hz), rated voltage to 690V, rated current from 3A to 100A, and adjustable operating current from 0.12A to 100A The current under the specified abnormal conditions (such as short circuit) can be connected, carried and broken.

In terms of its structure and function, KB0 series products are no longer single products such as contactors, circuit breakers, or thermal relays, but a set of control and protection systems. Its appearance fundamentally solves the problems of unreasonable control and protection coordination caused by unreasonable selection of traditional discrete components (usually circuit breakers or fuses + contactors + overload relays), especially overcoming various problems. Due to the inconsistency between the protection characteristics and the control characteristics when the electrical products with different assessment standards are combined, the operation reliability and continuous operation performance of the control and protection system are greatly improved.
