Abstract
A small breaker is disclosed. A wiring frame and a connecting piece of a conventional small breaker are connected through welding, assembly is complicated, and work efficiency is low. The small breaker comprises an integrated wiring frame (2) including a wiring pedestal (21) and a connecting plate (22) extending on the wiring pedestal (21). Bimetallic strips (3) are connected to the connecting plate (22), and a wiring nut (4) is installed in the wiring pedestal (21). A wiring nut is installed on the integrated wiring frame, and a connecting plate is extended on the wiring pedestal for connecting the bimetallic strips. The small breaker is easy for assembling, simple in structure and convenient for use.
