Abstract:The design of MCB-based self-reset over-voltage / under-voltage protector is proposed based on the analysis of relay / contactor-type sel-reset over-voltage / under-voltage protector. Voltage sampling,CPU control,motor drive and position detection circuit of MCB-based over-voltage / under-voltage protector are introduced.
