Problems solved by technology

However, in this installation process, the power supply of the line is discontinuous, and the power outage time is long, so it is not suitable for the installation, removal and maintenance of industries such as data centers and communication power supplies that require continuity of power supply.
In addition, due to the card installation, although its stability is better, it is still prone to shift or fall off in an environment with severe vibration

Abstract

The invention discloses a base for a miniature circuit breaker. The base comprises two power input seats and two mounting guide rail assemblies. The two power input seats are fixedly arranged on the mounting guide rail assemblies respectively. Each power input seat is provided with a binding post assembly having a power input socket. Each mounting guide rail assembly includes a fixing member, a top plate and a pushing screw. The fixing member comprises a fixing base plate part, support plate parts extending upward from the two side ends of the fixing base plate part, and slide plate parts bentand extending from the tops of respective support plate parts toward the adjacent support plate parts. A gap is arranged between the two slide plate parts in each mounting guide rail assembly. The top plate is located between the two support plate parts of the mounting guide rail assembly and between the fixing base plate part and the bottom wall of the power input seat. The top plate is providedwith a screw hole matching the pushing screw. The base has high installation strength and is not liable to displace or fall off..

Description

Technical field [0001] The invention belongs to the technical field of power circuit breakers, and in particular relates to a base for small circuit breakers. Background technique [0002] In the prior art, the miniature circuit breaker generally adopts the C45 rail installation method, specifically, the bottom of the miniature circuit breaker is clamped on the C45 standard rail. , The circuit breaker has a wiring frame on the upper and lower sides, and it is compressed with the power supply side and the load side by wire connection screws. When the product fails and needs to be repaired or replaced, first disconnect the power supply, then remove the wire, remove the product from the rail, install a new product, connect the wiring, and then turn on the power supply. This card installation method is simple and easy to implement, has been widely used, and is the current mainstream. However, in this installation process, the line power supply is discontinuous and the power outage ...
