Abstract
The invention discloses a two-pole compact miniature circuit breaker. The breaker comprises a shell. The shell is internally provided with two protection poles. An operation contact mechanism is arranged between the two protection poles. Each protection pole comprises a short circuit protection mechanism, an arc extinguishing mechanism and an overcurrent protection mechanism, wherein the short circuit protection mechanism is in matched connection with the operation contact mechanism, the arc extinguishing mechanism is located at the bottom of the short circuit protection mechanism, and the overcurrent protection mechanism is located at the bottom of the operation contact mechanism and is in matched connection with the operation contact mechanism. A handle is arranged on the top of the shell and is connected with the operation contact mechanism, and buckles are arranged at the bottom of the shell. The two-pole compact miniature circuit breaker is small in size, the modulus thickness of the two poles is only 18 mm, the occupied space is small, materials are saved by about more than 40 percent, and the manufacturing cost is low.
Description
technical field [0001] The invention relates to a circuit breaker for low-voltage electrical appliances, in particular to a two-pole compact miniature circuit breaker for overcurrent protection and short circuit protection. Background technique [0002] The circuit breaker is the most widely used terminal protection electrical appliance. The module thickness of both poles of the circuit breaker currently on the market is 36mm. Due to the large module thickness of the two poles and the large overall volume, it can be assembled with variable There will be very little space and the scope of use is limited. Contents of the invention [0003] In order to solve the technical problems of the above-mentioned circuit breaker, the present invention provides a two-pole compact miniature circuit breaker with small volume, small use space and small two-pole modulus thickness. [0004] To achieve the above object, the technical scheme of the present invention is as follows: [0005] A...
