Problems solved by technology
[0004] The object of the present invention is to provide an electronic molded case circuit breaker to solve the above-mentioned background technology. When the original circuit breaker is installed and debugged, wiring needs to be installed on the upper and lower sides of the device, and usually several lines of wiring are required for installation, requiring work. The personnel fix the cable with one hand and tighten it with the other hand, which makes the operation more troublesome and reduces the efficiency of the installation work

The invention discloses an electronic molded case circuit breaker which comprises a circuit breaker casing body, an output end junction box and an input end junction box. The circuit breaker casing body is provided with an opening and closing handle. The opening and closing handle and the circuit breaker casing body are slidably connected. A mounting screw hole is arranged in the outer side of thecircuit breaker casing body. The input end junction box and the output end junction box are fixed on the upper side and the lower side of the circuit breaker casing body respectively. A limit seat and a rotating limit roller are arranged in the output end junction box of the device. Anti-slip lines are arranged on the surface of the limit roller. When wiring is carried out, a cable can be inserted into an output end crimping seat, and then the limit roller is rotated to fix the cable. A bolt on the outer side of the output end crimping seat can be easily tightened, which is convenient for anoperator to carry out quick installation, and increases the safety of the outlet end of the device. The possibility of cable exposure is reduced. Maintenance and debugging are safe.
Description
technical field [0001] The invention belongs to the technical field of electric devices, and in particular relates to an electronic molded case circuit breaker. Background technique [0002] The molded case circuit breaker can automatically cut off the current after the current exceeds the trip setting. Molded case refers to the use of plastic insulators as the casing of the device to isolate conductors and grounded metal parts. Molded case circuit breakers typically contain thermal magnetic trip units, while larger models have solid state trip sensors. [0003] When the original circuit breaker is installed and debugged, wiring needs to be installed up and down the device, and usually several lines of wiring are required for installation. Operators need to fix the cables with one hand and tighten them with the other. The operation is cumbersome and reduces the efficiency of installation work. Contents of the invention [0004] The object of the present invention is to p...
