The key connection point of the plastic-cased circuit breaker for electronics is the manually used or motorized connection. After the main connection is switched off, a free traction mechanism locks the main connection at the connection site. The solenoid coil of the overcurrent striker and the thermal component of the thermal striker are connected in series with the main circuit, and the solenoid coil of the undervoltage protection striker is connected in parallel with the power supply.

Electronic device molded case circuit breaker circuit short-circuit fault or heavy load, the synchronous motor of the overcurrent flow disconnector is suction, so that the random power off organization work, the main connector to disconnect the main circuit.
When the electronic device molded case circuit breaker circuit is overloaded, the thermal components of the thermal disconnectors are hot, bimetallic bending, so that the random disconnecting organization is working, the main contact breaks the main circuit.
When the electronic device molded case circuit breaker circuit working voltage is not enough, the working voltage striker synchronous motor released, random off the organization also work in, the main contact breaks the main circuit.
Pressing and holding down the sub-excitation regulator disconnect button, the synchronous motor of the sub-excitation regulator disconnect will be suctioned, so that the casual disconnect organization is working, and the main contact disconnects the main circuit.
Classification of electronic devices molded case circuit breakers.
Low-voltage circuit breakers are categorized based on the arc-absorbing substance to carry out the categorization. It is a circuit breaker that uses gas as the arc-suppressing substance. It is called a gas circuit breaker (air leakage switch). The circuit breaker with rare gas as the arc extinguishing substance is called rare gas circuit breaker (inert gas power switch), and the circuit breaker with oil as the arc extinguishing substance is called oil circuit breaker (oil power switch)
Difference between an electronic device molded case circuit breaker and a molded case circuit breaker.
Difference: leakage circuit breakers are accurately called leakage-protected plastic case circuit breakers. In other words, the key difference is the elevation of the leakage maintenance role over the role of the plastic case circuit breaker. Other overvoltage protection, overcurrent protection, tapping and other roles are the same.
