Problems solved by technology

The other is installed in an external leakage module (split CBR). When the residual current protection function is required, the module is installed at the outlet end of an ordinary molded case circuit breaker to perform the function of residual current protection. The reset must be manually reset by pressing the reset button. This form often increases the size of the CBR after an external module is connected.

Abstract

The invention relates to a manual and automatic combined residual current tripping device which comprises a base assembly, a middle assembly and a support assembly, wherein the base assembly comprises a base and a micro switch; the middle assembly is inserted in a groove of the base of the base assembly; and the support assembly is arranged on the middle assembly and is fixed on the base by the micro switch of the base assembly. Compared with the prior art, the tripping device has the advantages that the volume is compact, the reaction is sensitive, the automatic reset can be realized by the virtue of the further buckle of a breaker mechanism, the manual reset can be carried out by a manual reset button, and the like.

Description

technical field [0001] The invention relates to a residual current release, in particular to a manual and automatic residual current release. Background technique [0002] The residual current release is the executive mechanism of the CBR residual current protection function. When a leakage fault occurs in the system, the residual current release receives a control signal from the electronic controller and executes a mechanical action to trip the CBR, thereby breaking the circuit The purpose of the device to protect lines and equipment. At present, there are roughly two forms of residual current release installation: one is directly installed inside the molded case circuit breaker (integral CBR), this form is mostly a CBR with a single break point structure, and the reset of the leakage release is mainly When the circuit breaker mechanism is re-triggered, the residual current release is driven to reset. The other is installed in an external leakage module (split CBR). When...
