Problems solved by technology

[0002] Existing circuit breakers are generally displayed in two different colors when they are turned on and off. The difference is that when it is used, it is easy to misjudgment, which affects the normal use of the circuit breaker, and the existing circuit breaker structure is not stable enough, it is easy to cause unstable take-off and safety problems during long-term use, and Arcs are easily generated inside the existing circuit breakers, and it is difficult for existing circuit breakers to effectively extinguish the arcs, which is harmful to electrical appliances

Abstract

The invention relates to the technical field of switching devices, in particular to a circuit breaker with an on-off and take-off three-color indication structure, which comprises a shell, a bracket is arranged at the upper part in the shell, a handle is arranged at the top of the bracket, an indicator is arranged at one side of the handle, and a contact support arm is arranged in the shell and connected with the lower part of the handle. According to the design of the invention, various states can be respectively displayed through the three states of the disconnection indication area, the take-off indication area and the connection indication area by the indicator, the problem of misjudgment is avoided, flexible disconnection of the device during current overload can be facilitated through the tripping mechanism, safe use of the device is guaranteed, and an arc can be conveniently led into the arc extinguishing chamber through the end tab horizontally arranged on the lower portion inthe shell, so that the arc is eliminated.

Description

technical field [0001] The invention relates to the technical field of switching devices, in particular to a circuit breaker with a three-color indication structure for on-off and take-off. Background technique [0002] Existing circuit breakers are generally displayed in two different colors when they are turned on and off. The difference is that when it is used, it is easy to misjudgment, which affects the normal use of the circuit breaker, and the existing circuit breaker structure is not stable enough, it is easy to cause unstable take-off and safety problems during long-term use, and An electric arc is easily generated inside the existing circuit breaker, and it is difficult for the existing circuit breaker to effectively extinguish the arc, which is harmful to electrical appliances. Contents of the invention [0003] The object of the present invention is to provide a circuit breaker with a three-color indicator structure for on-off and take-off, so as to solve the ...
