Circuit Breakers

Circuit breakers are as essential as your electrical grid or power lines. They are safety devices designed to protect electrified systems from damage and explosions by instantly shutting off the power supply when current reaches a certain level. APL11-4088-6 circuit breaker is a High Voltage Air Circuit Breaker (HVACB) designed for reliable and safe switching of all types of loads. In this article, we will discuss its application field and the principle of its working.

Application Field

APL11-4088-6 Air Circuit Breaker is ideal for almost all electrical systems operating at energy levels above 3.6 KV. The applications of this circuit breaker include power cut-off, short circuit protection, manual switching, motor circuit protection, transformer switching, etc. It is widely used in substation and power plant. It is also applicable to auxiliary circuit control system in transformer substations and distribution networks.

Working Principle

APL11-4088-6 circuit breaker works by interrupting the flow of current of the overcurrent circuit. When the current exceeds the set limit, a magnetic field is generated, causing the breaker to trip and stop the flow of electricity. This trip is activated through the use of an electromagnetic field and a set of contacts. When the breaker is in operation, a solenoid is activated and the force it produces opens the set of contacts and interrupts the circuit, stopping the current flow. If current drops below the set limit, the breaker will return to its normal position and resume the flow of electricity.

Conclusion

APL11-4088-6 air circuit breaker is especially designed to meet the needs of high-voltage electrical systems. As a safety device, this circuit breaker has many applications and is widely used in substation and power plant. It works by interrupting the flow of an overcurrent circuit and can be reset when the current drops below the set level.
