JBTK1 Control and Protection Switch


JBTK1 series control and protection switch electrical appliances are integrated, internally coordinated and cooperated of control and protection functions in a single structural form of products, which can replace circuit breakers (fuses), contactors, starters, isolators, thermal relays, overload (or overcurrent, phase breaker) protection relays, motor integrated protectors, intelligent leakage relays and other traditional separation components, with long-distance automatic control and local manpower control and control of the way to control the operation function. It has the characteristics of time-current protection of coordinated cooperation, has the advantages of controlling and protecting self-cooperation, continuous operation after short circuit, high breaking ability, small arc distance, long life, adjustable protection and setting current, convenient operation, and a variety of supporting accessories and modules, which can realize the control and protection of motor load and distribution load.



JBTK1 series control and protection switch electrical appliances based on the latest microelectronics technology, on the basis of peer products, developed a JBTK1 series of control and protection switch electrical appliances with the characteristics of the company, to overcome the shortcomings of peer products, bringing together the advantages of low-voltage electrical discrete components, complete functions, reliable performance, for low-voltage distribution and control system simplification and optimization provides a basic component.
