Problems solved by technology

The first type of RCBO has the same width as the compact product, but because the leakage detection and the N-pole connecting flexible wire are located on the left side of the product, the length of the product is longer, so a special distribution box is still required for installation. N pole connection soft wire does not have the basic protection function of RCBO, resulting in poor reliability of the product
The second type of RCBO has the same size as the compact product, but lacks N-pole connecting flexible wires, which makes the product installation cost higher and the convenience of user wiring needs to be improved

Embodiment approach

[0048] In order to facilitate users to manage and use the circuit breaker more easily, different from the prior art, the residual current operated circuit breaker of the present invention realizes the N-pole outgoing line through the flexible wire assembly 60, and the flexible wire assembly 60 has an opening and closing contact Function to enhance the electrical safety and reliability of the N-pole current loop. Combine figure 2 with Figure 4 As shown, the flexible wire assembly 60 is accommodated in the second accommodation chamber. According to a preferred embodiment of the present invention, the incoming end of the third terminal assembly 51 and the outgoing end of the flexible wire assembly 60 are located on the same side of the housing 10. The above design facilitates product installation and Wiring, improve the user's space utilization. Because the structural design inside the shell is more compact, and the overall length of the circuit breaker product remains unchange...

Abstract

The invention provides a residual current operated circuit breaker. The circuit breaker includes: a housing; an electromagnetic tripping device and an arc extinguishing device; a first operating mechanism and a second operating mechanism; a leakage tripping device; a first terminal assembly, the mounting housing There is a mounting gap on one side, and the first terminal assembly can penetrate the mounting gap and be clamped in the space formed by the first housing and the second housing; a second terminal assembly is housed in In the first accommodation chamber; a third terminal assembly, which is accommodated in the second accommodation cavity; and a flexible wire assembly with a function of opening and closing contacts, which is accommodated in the second accommodation cavity. According to the residual current-operated circuit breaker of the present invention, the protection function of the product is more perfect, the structural layout of the housing is more compact, and the product installation and wiring processes are more convenient and reliable.

Description

Technical field [0001] The invention relates to the field of low-voltage electrical appliances, and in particular to a residual current operated circuit breaker. Background technique [0002] As we all know, in addition to the control, overload, and short-circuit protection functions of traditional miniature circuit breakers (MCB), leakage circuit breakers also have leakage protection functions, which can play a positive role in protecting human life and property safety. Quickly cut off the faulty power supply within time to protect the safety of people and electrical equipment. [0003] The existing RCBOs are usually divided into the following two implementation modes according to their own structural layout. The first type of RCBO has the same width as the compact product, but because the leakage detection and the N-pole connecting flexible wire are located on the left side of the product, the product length is longer, so a special distribution box is still needed for installati...
