Circuit Breakers: IALK1-1-71-1.00-01 Application Field and Working Principle

Circuit breakers are devices that prevent overloading or short circuits from damaging electrical devices and systems. The IALK1-1-71-1.00-01 circuit breaker is a compact, high-performance breaker specifically designed for use in aviation applications. This article will discuss the application field and working principle of the IALK1-1-71-1.00-01 circuit breaker.

Application Field

IALK1-1-71-1.00-01 circuit breakers are designed with many features to make them ideal for use in aviation applications. These include an IP rate of between 35 and 85, a wide temperature range (between -55°C and +185°C), and a switching voltage of 28VDC. They are also designed with a short-circuit withstand capability of 15,000A and a high current rating of up to 160A. Additionally, the IALK1-1-71-1.00-01 circuit breaker has a low leakage current rating of 10µA, making it perfect for low power avionics applications.

Working Principle

The IALK1-1-71-1.00-01 circuit breaker functions on the principle of a thermal-magnetic trip unit. When the current flowing through the breaker exceeds the trip current for a specified period of time, the time-delay action of the thermal-magnetic trip unit causes the breaker to trip and isolate the circuit from power. The thermal element in the trip unit is designed to protect electronics from short-duration overcurrents and surges, while the magnetic trip element is designed to protect the equipment from large, sustained overcurrents.

Conclusion

The IALK1-1-71-1.00-01 circuit breaker is a high-performance breaker designed specifically for use in aviation applications. It is designed with an IP rate of between 35 and 85, a wide temperature range, a switching voltage of 28VDC, and a short-circuit capability of 15,000A. It is also designed with a low leakage current rating of 10µA and a current rating of up to 160A. The IALK1-1-71-1.00-01 circuit breaker functions on the principle of a thermal-magnetic trip unit. When the current flowing through the breaker exceeds the trip current for a specified period of time, the time-delay action of the thermal-magnetic trip unit causes the breaker to trip and isolate the circuit from power.
