Integrated residual current operated circuit breaker with current leakage indication function

Abstract

The invention discloses an integrated residual current operated circuit breaker with a current leakage indication function. A current leakage tripping unit and a circuit breaker unit adopt an integrated design, the integrated residual current operated circuit breaker comprises an upper cover, a middle cover, a base, an indicator, a reset button, a reset spring, a test button, a current leakage indicator, an indication window, an operating part, a current leakage switch and a dripping mechanism, wherein main electric functional components are arranged in an integrated housing, the indication window and the current leakage indicator are arranged on the housing, and one end of a load current leakage tripping unit is lengthened for setting the reset button, the reset spring, the indicator, the current leakage indicator and other reset and indication devices. According to the integrated residual current operated circuit breaker disclosed by the invention, the main circuits of both electrodes are provided with overcurrent protection functions and are provided with independent and obvious divide-shut brake indicators, the current leakage indicator occupies no space of the divide-shut brake indicators of the main circuits and can perform independent indication and reset, the protection and fault state of the circuit breaker are clear at a glance, and an independent current leakage switch is set to open and close the current leakage function so as to meet diversified demands of users.

Description

technical field [0001] The invention relates to the field of low-voltage electrical technology, in particular to an integrated residual current operated circuit breaker with leakage indication. Background technique [0002] The residual current operated circuit breaker is a multifunctional circuit breaker that combines the function of detecting residual current and disconnecting the main circuit, and can also protect the circuit from overload and short circuit. When the specified value is exceeded, the residual current operated circuit breaker can quickly cut off the faulty power supply in a very short time to protect the safety of people and electrical equipment. At present, the traditional residual current operated circuit breakers used for smart meter box control are combined 2P residual current operated circuit breakers, which have the disadvantages of large product volume, large installation space, and unreasonable design of the closing indication structure inside the p...
