A bipolar circuit breaker comprises a shell, as well as two arc-extinguishing devices, two contact assemblies, an operating mechanism, two electromagnetic protection devices for driving the operating mechanism respectively, and two thermal protection devices which are installed inside the shell, wherein the operating mechanism is installed on the middle part of the shell; the two electromagnetic protection devices are positioned on the two sides of the operating mechanism respectively; the two thermal protection devices are positioned between the electromagnetic protection devices and the operating mechanism respectively; the two arc-extinguishing devices are positioned below the two electromagnetic protection devices; and the contact assemblies are positioned inside arc-extinguishing chambers of the arc-extinguishing device. The bipolar circuit breaker has the advantages as follows: the bipolar circuit breaker is compact in structure, simple in layout and small in volume; compared with the conventional bipolar circuit breaker, the width of the shell of the bipolar circuit breaker provided by the invention is reduced, raw materials are saved, the application range of the bipolar circuit breaker is expanded; and a middle base is arranged inside an installing cavity of the shell, so that components can be conveniently installed and fixed and the assembling efficiency of the bipolar circuit breaker is improved.
Description
technical field [0001] The invention relates to a circuit breaker, in particular to a double-pole circuit breaker. Background technique [0002] At present, the widespread use of circuit breakers has prompted the development of standardized circuit breaker housing sizes, for example, single-pole circuit breakers for residential and / or lighting, which are commonly sold in Europe, are accommodated in 18 mm wide housings. Likewise, Single pole circuit breakers for residential and lighting, commonly sold in the United States, are housed in 0.75 inch wide housings. Therefore, careful allocation of the 18 mm wide enclosure interior space can increase the number of circuit protection devices within an enclosure for a given enclosure size. At the same time, there have been modules on the market that accommodate two active poles within the standard housing size for single-pole circuit breakers, but their structures are complex, and the installation of components is troublesome and i...
