External circuit breakers and reclosing miniature circuit breakers (hereinafter referred to as electrically operated load switches) for electric energy meters are the new generation of multifunctional electric integrated distribution protection switches developed by our company for the actual use environment of safe and energy-saving electricity in urban and rural areas. They solve the problem of frequent manual operation and management, and work together with prepaid electric energy meters to achieve high breaking miniature electric load switches that automatically open and lock after overdue payments, and automatically close after the electricity meter is powered on; This switch has a small external volume and can directly replace the original generation product, while meeting the reliable operation and management of intelligent power grids.

2、 Scope of application

Chengyang electric circuit breaker is suitable for power supply systems, industrial and mining enterprises, households and other three-phase four wire low-voltage power grids. It has a rated voltage of 230V~400V and a rated current of 40A~125A, and is used to protect remote computer control and line operation equipment in distribution areas from overcurrent, short circuit breaking, etc. Adapt to the installation of prepaid energy meters and terminal equipment in the distribution cabinet and power supply area incoming line meter box, which can achieve remote computer operation and intelligent management with the network system.
