The invention discloses a reclose breaker. The reclose breaker comprises a breaker module, an automatic reclose module and a power PCB board. The housing of the miniature breaker is provided with a plugged hole for plugging of the power PCB board. The housing of the automatic reclose module is provided with a connection hole. The connection hole is installed relative to the plugged hole. A female plug is embedded in the plugged hole. The plugged hole is provided with a connection sheet electrically connected with a connection terminal. One end of the power PCB board is provided with a power sheet, and the other end is provided with a male plug matched with the female plug. While the power is needed through the assembly, one end of the power PCB board is directly plugged in the plugged hole of the housing, the power sheet on the power PCB board is electrically connected with the connection sheet, and the male plug on the other end of the power PCB board is aligned to and matched with the female plug on the automatic reclose, so the power supply is realized. Compared with the traditional technology, the power sheet on the power PCB board is connected by plugging without the welding with the connection terminal of the breaker, and the power PCB board is connected with the automatic reclose module through the matching of the female plug and the male plug. The structure is simple, and the assembly is convenient.
