Overview
Using SSKBO as the main switch, a modular structure is adopted, integrating functions of low-voltage electrical products such as fuses, circuit breakers, contactors, starters, isolators, thermal relays, overload (or overcurrent, phase failure) protection relays, motor comprehensive protectors, intelligent leakage relays, etc. With appropriate reversible contactors, time relays, and other necessary accessories, a new type of protective star delta (Y - △) pressure reducing starter is formed through electrical interlocking
