Circuit Breakers

A circuit breaker is a device designed to protect an electrical circuit from damage caused by overload or short circuit. The 3400-P10-H-SI-5A is a specific type of circuit breaker that was designed for use in a harsh environment. This article discusses the application field of the 3400-P10-H-SI-5A and its working principle.

Application Field

The 3400-P10-H-SI-5A is designed to provide long-term endurance under a variety of conditions. The device is designed to operate in harsh environments, including high-temperature and high-humidity ones, by being constructed with a new dielectric material known as Hydrin. The device also has the ability to withstand strong vibrations and extreme shocks.

Due to its robust construction, the 3400-P10-H-SI-5A is often used in the military, industrial, and aerospace fields. The device can be used for a variety of applications, including protection and circuit switching. The device can also be used in low-voltage and medium-voltage applications.

Working Principle

The 3400-P10-H-SI-5A works by using a combination of electrical and mechanical components. The device contains a thermal-magnetic trip unit, which consists of both a thermal element and a magnetic element. The thermal element operates by detecting a high temperature, while the magnetic element operates by detecting a high-current overload.

When a fault such as an overload or short circuit is detected, the device trips and disconnects the circuit. This protects the rest of the circuit from sustained damage. The device can also be reset manually, allowing it to be used multiple times.

Conclusion

The 3400-P10-H-SI-5A is a robust circuit breaker designed for use in harsh environments. The device has the ability to withstand high temperatures, high humidity, strong vibrations, and shocks. It is often used in the military, industrial, and aerospace fields, and can be used for a variety of applications such as protection and circuit switching. The device works by using a thermal-magnetic trip unit, which trips and disconnects the circuit when a fault is detected.
