What do you know about DC Molded Case Circuit Breakers?

There are various types of DC Molded Case Circuit Breakers on the market, and each style of circuit breaker works in its own way. The DC Molded Case Circuit Breaker is generally installed at a relatively low altitude, otherwise the DC circuit breaker will not work properly. In addition, the requirements of DC Molded Case Circuit Breaker for the surrounding environment are also more complicated. It can't be higher than forty degrees and it can't be minus five degrees in hell.

What is the structural difference between the DC Molded Case Circuit Breaker and the AC Molded Case Circuit Breaker?

What are the wiring methods of the DC Molded Case Circuit Breaker?

How does the DC Molded Case Circuit Breaker work?

What is the structural difference between the DC Molded Case Circuit Breaker and the AC Molded Case Circuit Breaker?

1. Structural composition of AC Molded Case Circuit Breaker: AC Molded Case Circuit Breaker includes a shell, a high-voltage porcelain bottle set on the shell, a three-phase high-voltage input end, and a three-phase high-voltage output end. Electrodes, fixed electrodes and controllers, the linear electromagnetic pusher includes an iron core, a coil, a permanent magnet, an armature, a push rod and an electromagnetic positioning lock, and a push rod is arranged between the movable electrode and the linear electromagnetic pusher.

2. Structure and composition of DC Molded Case Circuit Breaker: DC circuit breaker topology is complex and diverse. According to the different key breaking devices in DC Molded Case Circuit Breaker, DC circuit breakers can be divided into three categories: mechanical Hybrid DC circuit breaker combining solid state DC circuit breaker, mechanical switch and solid state switch.

What are the wiring methods of the DC Molded Case Circuit Breaker?

1. Wiring behind the board. The advantage of the wiring behind the board is that when maintaining the DC Molded Case Circuit Breaker, etc., it is only necessary to disconnect the power supply of the front stage without re-wiring. This type of structure is relatively special and is equipped with special mounting plates and screws. During installation, it must be installed in strict accordance with the manufacturer's requirements to avoid affecting the normal use of the circuit breaker.

2. Plug-in wiring. The advantage of plug-in wiring is that when the DC Molded Case Circuit Breaker needs to be replaced, simply unplug the old breaker and replace it with the new one. It is faster and more convenient to operate than the wiring before and after the board. When installing using this method, ensure that the plug is securely fastened, thereby reducing contact resistance and improving safety and reliability.

How does the DC Molded Case Circuit Breaker work?

The DC Molded Case Circuit Breaker combines power electronic devices and is a circuit breaker for breaking the DC circuit. The moment when the DC breaking is realized is the current zero-crossing point. DC circuit breakers can generally be divided into mechanical DC circuit breakers, solid-state DC circuit breakers and hybrid DC circuit breakers. Among them, the control of power electronic devices and DC arc extinguishing are the key technologies of DC circuit breakers.
