Problems solved by technology

[0005] However, in prior art circuit breakers, the different spaces between the individual phases (for example, R, S, T, and N phases) according to the breaking capacitance of each device make it impossible to universally use the trip unit module
[0006] In addition, since other devices performing additional functions of the trip alarm function and the delay output function should be installed in the main body of the circuit breaker, the size of the main body of the circuit breaker may increase, and assembling them requires a lot of time and effort
In addition, in the case of synchronous or interworking of various devices, it is difficult to improve the operating reliability of the circuit breaker

Abstract

Disclosed are a trip device module and a circuit breaker having the same, the trip device module including: a case having first and second arm receiving pockets to receive and accommodate driving arms disposed at a main shaft of various different inter-phase spacings; an actuator received in the case and having an output portion drawn out or introduced thereinto when the overcurrent relay outputs the trip signal; a reset plate installed in the case to interwork with the main shaft so as to initialize the output portion of the actuator; and a trip slider configured to allow the switching mechanism to perform the tripping operation when the actuator performs the trip operation, whereby the same trip device module can be commonly used for devices with different inter-phase spacings, and a compact configuration and operational reliability can be ensured.

Description

technical field [0001] The present invention relates to a tripping device module and a circuit breaker for implementing the tripping device module, in particular to a tripping device module and a circuit breaker for realizing the tripping device module that can be used in devices with different spaces between phases. Background technique [0002] The so-called circuit breaker refers to an electrical protection device that is installed between the power supply and the load equipment to protect the load equipment and the power supply line from the fault current that may occur in the circuit (short circuit, overload current due to ground fault, etc.) . [0003] The circuit breaker includes a switch mechanism for switching a fixed contactor and a movable contactor; an overcurrent relay for detecting a fault current and outputting a trip command to block conduction of an overload current; and a tripping device module provided at the switch Between the mechanism and the overcurre...
