Background

The miniature circuit breaker is composed of an operating mechanism, contacts, a protection device (various releases), an arc extinguishing system and the like. The main contact is manually operated or electrically switched on. After the main contact is closed, the free tripping mechanism locks the main contact at the closing position. The coil of the over-current release and the thermal element of the thermal release are connected with the main circuit in series, and the coil of the under-voltage release is connected with the power supply in parallel. When the circuit is short-circuited or seriously overloaded, the armature of the overcurrent release is attracted, so that the free release mechanism acts, and the main contact breaks the main circuit. When the circuit is overloaded, the thermal element of the thermal release heats up to bend the bimetallic strip and push the free release mechanism to act. When the circuit is under-voltage, the armature of the under-voltage release releases, and the free release mechanism also acts.

However, with the development of science and technology, various requirements of people are gradually increased, for example, in places such as hotels, chain stores, and nursing homes, customers want to know the real-time power consumption of each main circuit, that is, need to know more detailed power consumption data, and want to view the data in real time, and the data needs to be displayed visually.
