Many people wonder what role the plastic case switch plays and why it is used in many industries. In fact, those who know this machine know that it plays a very important role and has a very significant meaning. So, what can a plastic case switch bring to the table? Why not follow the plastic case switch manufacturer and explore, you may find many surprises.

The first type of moulded case switch has the ability to limit the disconnection current. When a circuit breaker is short-circuited or in contact with an arc, the use of a moulded case switch is equivalent to increasing the arc resistance, which minimises circuit faults. Reducing the disconnection time of a circuit breaker indicates an increasingly effective current limiting effect, as well as reducing the electromagnetic, electrical and thermal impact of a short circuit on electrical equipment, thus extending the life of the breaker.

Secondly, the plastic case switch can act as a short circuit protection, i.e. a short circuit causes a momentary trip. It is important to note that a plastic case switch is required at this time after a change in load or when you want to protect the machine. It prevents frequent tripping from harming the quality of the power supply and also provides good protection for electrical equipment.

Thirdly, the plastic shell switch can develop the role of overload delay protection, the so-called delay protection work is when the impact of overload current and the management of electrical equipment to produce serious harm, the plastic shell switch can immediately cut off the power supply, try to avoid the use of machine learning by environmental damage. Everyone we should know that overload is a student accumulation of heat, this action does not need to be particularly need to be fast. It is only necessary to study it for protection when the current is overloaded.

Fourth, the plastic case switch has an isolation function, the so-called isolation function is to prevent damage to people or machines caused by leakage after a power failure. Multiple trips will greatly reduce the switchability of the machine and the leakage current will increase. If the environment is particularly harsh, the leakage current can exceed two hours, which can damage insulated equipment and cause a fire. A plastic case switch can be an excellent fire protection device.

A plastic case switch can provide protection against leakage currents, and electromagnetic leakage interference is not good compared to electronic leakage. When the leakage current reaches a certain value, it will pose a threat to machines and people. At this point if a plastic switch is used, the release can be made to disconnect automatically and when the device is no longer energised it will not leak. This not only protects personal safety and machine safety, but also avoids waste.
