Circuit breakers are a class of electrical and electronic devices designed to provide a measure of protection against an overload or short circuit in an electrical circuit by disconnecting the circuit automatically when the current exceeds a preset limit. The GMB63H2PC10 is one such device, a three-phase circuit breaker designed to be used in high-voltage electrical systems. In this article, we’ll explore the application field and working principle of this device in more detail.

First, let’s look at the application field of the GMB63H2PC10. This device is designed as a three-phase medium-voltage circuit breaker. According to the manufacturer’s specifications, it is suitable for operation in electrical systems with voltages up to 6.3kV and currents up to 800A. It is frequently used in installations such as water utilities, energy distribution networks, industrial and commercial power systems, and emergency power supply systems.

Now let’s examine the working principle of the GMB63H2PC10 circuit breaker. It consists of three parts: a stationary contact, a movable contact, and a trip mechanism. When the device is off, the stationary contact is connected to the load, allowing current to flow through the system. When too much current is detected (known as an overload or short circuit), the trip mechanism trips, pushing the movable contact away from the stationary contact and breaking the connection, which causes the electric circuit to be interrupted.

The trip mechanism can be activated either by a manual switch or by a thermal (or overload) element. The thermal element is designed to detect an overload in the system, and it trips the breaker if it detects too much current passing through. The thermal element works by sensing the temperature increase that results from too much current passing through the circuit. This increase in temperature is detected by a bi-metal strip, which then trips the breaker.

The GMB63H2PC10 is designed with a number of safety features, including a mechanical/electrical/thermal release system, which serves to ensure a quick and effective response to an overload or circuit fault. It also features an earth leakage protection system designed to protect against earth faults and to ensure a safe and secure switching environment.

The GMB63H2PC10 circuit breaker is a reliable and efficient device designed to protect against electrical overloads and faults in high-voltage systems. Its application field includes water utilities, energy distribution networks, industrial and commercial power systems, and emergency power supply systems, and its operation is based on detecting an overload in the system and then tripping an associated circuit breaker. It is designed with a variety of safety features, including mechanical/electrical/thermal release systems and earth leakage protection, to ensure efficient and safe operation in the intended application field.
