The low-voltage circuit breaker has the advantages of various protection functions (overload, short circuit, under-voltage protection and the like), adjustable action value, high breaking capacity, convenience in operation, safety and the like, so that the low-voltage circuit breaker is widely applied.

The main contacts of the low-voltage circuit breaker are manually or electrically switched. 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 undervoltage, the armature of the undervoltage release is released. The trip free mechanism is also actuated. The shunt release is used for remote control, when the shunt release works normally, the coil is powered off, and when the shunt release needs to be controlled for distance, the start button is pressed to enable the coil to be powered on.
