Overview
Using SSKBO as the main switch, it integrates functions such as fuses, circuit breakers, contactors, starters, isolators, thermal relays, overload (or overcurrent, phase failure) protection relays, motor comprehensive protectors, intelligent leakage relays, and other low-voltage electrical products. Together with corresponding enamel contacts and other necessary accessories, it forms a new type of protective SSKBOD dual speed motor control and protection switch device through mechanical and electrical couplings, achieving integrated internal coordination and coordination of dual speed motor automatic control and various protection functions, suitable for the start control and protection of dual speed motors. It has the same characteristics as star delta pressure reducing starter and self coupling pressure reducing starter. The product is equipped with electrical connectors as needed, which have the advantages of high reliability, high segmentation ability, high lifespan indicators, small size, small installation area, and low installation and maintenance workload
Model and meaning

Configuration type
High speed is fire protection type (overload, overcurrent only alarm without tripping), low speed is basic type
Both high and low speeds are basic types
Both high and low speeds are of the fire-fighting type
