Circuit breakers are devices in electrical systems that protect them from overload and short circuits. Electrical appliance designers use them for safety purposes, as they quickly shut off power when the current reaches a certain level. UPL113-1864-10 is an example of a circuit breaker commonly used for small to medium sized power supplies, and it includes a range of features that provide a robust protection system. This article will discuss the application field and working principle of this particular breaker.

The UPL113-1864-10 circuit breaker is suitable for use with various types of power supplies. It is particularly suited to non-DC, AC and DC applications. It is also suitable for a variety of industries, including but not limited to: aviation, power electronics, marine, telecommunications and industrial automation. The comprehensive protection provided by the UPL113-1864-10 also makes it an ideal choice for installations in hostile environments, such as those that are exposed to corrosive fluids or extreme temperatures.

In terms of the working principle, the UPL113-1864-10 circuit breaker works by cutting off the electrical flow when it reaches a certain level. This is achieved with the help of a bimetallic strip, which is a device with two layers of different metals with different thermal expansions. When the current increases, it causes one metal to expand more than the other. This then triggers the action of the breaker by pushing a contactstrip, and this ends up disconnecting the circuit. This process is done within milliseconds and helps to avoid a possible tragedy that may arise if the circuit was left working with an overload.

In order to ensure consistent and reliable performance, the UPL113-1864-10 circuit breaker also features a series of important safeguards. Firstly, the device includes temperature stages which allow it to adjust the thermal expansion of the bimetallic strip and thus limits the maximum current that can flow before it gets to a dangerous level. Additionally, the device includes several other components such as a trip lever, reset device and current sensing coils, all of which act together to ensure that the circuit is safely disconnected when needed.

In conclusion, the UPL113-1864-10 circuit breaker is an excellent electrical system protection device. It is suitable for many types of power supplies and industries, including hostile environments. The device uses a bimetallic strip and various other components to quickly and safely cut off the power when a certain current level is reached. As such, many designers choose the UPL113-1864-10 for their circuit protection requirements.
