Circuit Breakers: IEGBX6-35130-10-V application field and working principle

Circuit breakers are used as safety devices in electrical systems to protect against overloads, short circuits and ground faults, thereby ensuring safe operation of circuits. This article introduces the application field and working principle of the type IEGBX6-35130-10-V circuit breaker.

Application Field

The IEGBX6-35130-10-V circuit breaker is a high-performance, high-current and low-voltage circuit breaker designed for industrial and mining applications. This type of circuit breaker has many advantages, such as reliable performance, small volume, strong fault-withstanding capacity, low contact resistance, easy maintenance and so on.

Specifically, it is suitable for power distribution system and frequent switch operation. It is suitable for AC 50/60Hz, rated voltage 690V, rated current up to 3200A. It has a high breaking capacity of 415 KA to protect circuits in case of an overload or short circuit.

Working Principle

The IEGBX6-35130-10-V circuit breaker consists of a main contact and an auxiliary contact. The main contact connects the electricity supply, while the auxiliary contact monitors the current flow. When the current exceeds the set limit, the thermal element in the circuit breaker heats up and pushes the arc extinguishing plate against the main contact, disconnecting the power supply and preventing current from flowing.

The arc extinguishing plate works in combination with the starting device. When the circuit breaker is switched on, the starting device sets the arc extinguishing plate in the "open" position, i.e. away from the main contact. The current then flows from the main contact to the load. When the current exceeds the rated value, the thermal element is heated and the arc extinguishing plate is pushed to the main contact, separating it and thus interrupting the current.

Conclusion

In conclusion, the IEGBX6-35130-10-V circuit breaker is a reliable, low-voltage device with features such as high breaking capacity and small volume. Its working principle is based on the thermal element and arc extinguishing plate, which protect against overloads and short circuits.
