GMB632PC30 Circuit Breakers: Application Field and Working Principle

Today, Circuit Breakers are becoming more and more popular in a range of applications due to their many advantages over traditional switching components. GMB632PC30 is one type of circuit breaker which is used in commercial and industrial buildings, as well as being particularly suitable for installations in commercial heavy-duty motor control and emergency power equipment. This article will discuss the application field and working principle of GMB632PC30 circuit breaker.

Application Field

The GMB632PC30 is highly rated for commercial and industrial applications, with a current rating of up to 630A and short circuit interrupting rating of up to 33,000A. It is designed to prevent overloading and short circuits in air-conditioners, refrigerators, lighting systems, and various other electrical and electronic equipment. The GMB632PC30 is also an excellent choice for installations requiring emergency power and industrial motor control, since it provides reliable protection for sensitive equipment and is suitable for both single and three-phase applications.

Working Principle

The GMB632PC30 circuit breaker is based on the principle of thermal-magnetic operation, which combines the benefits of both thermal and magnetic circuit breaker technologies into a single unit. The thermal element senses the current flowing through the breaker to determine when the current is higher than the current rating of the breaker. When the current exceeds its rating, the thermal element bypasses the magnetic element, which trips the circuit breaker and interrupts the current flow.The magnetic element on the GMB632PC30 circuit breaker also provides additional protection by sensing when a short circuit conditions occurs, where the current exceeds the short circuit interrupting rating of the breaker. When this occurs, the magnetic element immediately bypasses the thermal element, trips the breaker, and shuts off the current flow.

Conclusion

The GMB632PC30 circuit breaker is an ideal choice for commercial and industrial installations which require reliable protection from both overloads and short circuits. It is highly rated for current of up to 630A, and its short circuit interrupting rating of up to 33,000A ensures it provides reliable protection even in the most demanding applications. The breaker combines the advantages of both thermal and magnetic circuit breaker technologies into a single unit, making it an effective and reliable solution for protecting sensitive equipment from the destructive effects of electrical faults.
