Abstract

The invention is adapted to match with small-size circuit breakers, in particular to a shunt trip with an indicating function. According to the technical scheme provided by the invention, a base is provided with a cover, and a main shaft, a trip gear and an electromagnetic system are arranged inside the base. And the main shaft is arranged inside a hole on the upper right side of the base, and the trip gear can be rotatablely arranged on the main shaft. The electromagnetic system is disposed inside a retaining groove which is arranged on the upper left side of the base. The left and right sides of the base are respectively provided with a wire connecting terminal. The invention is characterized in that a wire connecting terminal C2/11 is connected to phase lines or a positive electrode of the power, a wire connecting terminal C1 is connected to an N line or a negative electrode of the power by employing a normally open push button, an indirect indicating lamb L1 is connected between a wire connecting terminal 12 and the N line or the negative electrode of the power, and an indirect indicating lamb L2 is connected between a wire connecting terminal 14 and the N line or the negative electrode of the power. The trip has the indicating function, which is capable of being judged whether the trip is in normal working, or at off-state when using the trip.

Description

technical field [0001] The invention is suitable for matching a small circuit breaker, specifically a shunt tripper with indicating function. Background technique [0002] Miniature circuit breakers used in the field of fire protection need to be matched with shunt releases. The purpose is to forcefully break the circuit at a long distance when the load controlled by the miniature circuit breaker has a fire or other fault, so as to reduce unnecessary economic losses. [0003] The shunt release matched with the current miniature circuit breaker generally has two structural forms: a, two-terminal structural form, this structural form does not have an indicating function, and it cannot be judged whether it is in a normal working state or a disconnected state; b. 1. Four terminal structure, this structure has indication function, but the internal wiring is more complicated, it is easy to break during the assembly process and long-term movement process and cause actual effect, an...
