AI Technical Summary

Benefits of technology

This technology allows for easier assembly or replacement of circuits that have been damaged by an overcurrent fault (OCP). By embedding certain holes inside a special board with multiple plates attached together, it becomes possible to connect different types of wires without causing damage from electrical arcs caused by current flowing between them. Additionally, this design makes installing these devices more efficient because they can be easily mounted onto existing equipment within limited spaces while still maintain their effectiveness at preventing any harmful power surges.

Problems solved by technology

This patented technical problem addressed by this patents relates to an issue with traditional single-In/One-Out (SISO) type circuit breakings used for lower voltages such as 500 V or less due to their bulky size when they were designed without taking into account factors like weight reduction and manufacturing costs associated therewith.

Abstract

The invention relates to a one-in two-out double-sided operation low-voltage molded case circuit breaker. The circuit breaker comprises a first circuit breaker mechanism, a second circuit breaker mechanism and a fixed base. The first circuit breaker mechanism and the second circuit breaker mechanism are arranged on the front side and the rear side of the fixed base respectively. The circuit breaker mechanism comprises a switch and a shell. The switch is arranged in the middle of the shell. The upper side of the shell is connected with four wire inlet binding posts in a screwed mode. The lowerside of the shell is connected with four wire outlet binding posts in a screwed mode. Four wire inlet holes are formed in the top of the shell, and the positions of the four wire inlet holes correspond to the positions of the four wire inlet binding posts. According to the invention, device disconnection caused by electric arcs in the later operation process can be avoided, so that two circuit breakers with the same model, the same shape and capacity and the same disconnection capability are combined into one. The installation space of the circuit breaker is reduced, and resources are saved.
