Abstract

The present invention is applicable to the technical field of electronic circuit breakers, and provides a molded case electronic circuit breaker for power distribution, which includes a circuit breaker body and an installation backboard for installing the circuit breaker body, and the circuit breaker body is snapped The mechanism is detachably connected to the installation backplane, and the installation backplane is also provided with a contact mechanism for connecting with the circuit breaker body. The contact mechanism includes an outer sleeve, a first contact and a second contact, wherein , the first contact is fixedly connected to the conductive column, the conductive column is fixed on the circuit breaker body and slidably fits with the outer sleeve, and the second contact for contacting the first contact is fixed inside the outer sleeve. point, the contact surface of the first contact and the second contact is plane, the beneficial effect of the present invention is: the installation of the backboard is used to realize the installation of the circuit breaker body, and the two are detachably connected by a buckle mechanism. It is more convenient to install, and in practical application, all the wiring harnesses required for connection can be hidden, and the safety performance is high.

Description

technical field [0001] The invention relates to an electronic circuit breaker, in particular to a molded case electronic circuit breaker for power distribution. Background technique [0002] The electronic leakage circuit breaker is mainly composed of a zero-sequence current transformer, an electronically controlled leakage release and a circuit breaker with overload and short-circuit protection. When there is leakage in the protected circuit or personal electric shock, as long as the leakage current reaches the design selected operating current value, the secondary winding of the zero-sequence current transformer will output a signal, and the circuit breaker will be activated through the leakage release, thereby cutting off the power supply. To leakage and electric shock protection. [0003] Circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to their scope of use. The division of high and low voltage boundaries is rel...
