Circuit Breakers are a vital component in electrical engineering, designed to protect circuits from excessive current, voltage or power. The IUGN1-1-52-5.00 Circuit Breaker is a particularly popular breaker designed by the Brazilian manufacturer Iguassu. It is a type 3-pole breaker and offers both AC and DC protection. In this article, we\'ll look at the application field and working principle of the IUGN1-1-52-5.00.

Application Field

The IUGN1-1-52-5.00 is an ideal choice for electrical protection in commercial and industrial buildings, as well as in any other settings where a high-quality circuit breaker is required. Thanks to its compact size, it can also be used in tight spaces where larger breakers wouldn’t fit. Additionally, its wide range of features, including thermal magnetic protection, over-current and under-voltage protection, makes it suitable for use in a variety of applications.

The IUGN1-1-52-5.00 is designed to last and can withstand even the most extreme conditions. It is certified to UL 891, which is the standard for circuit breakers in the US, and is rated for a continuous normal current of 400 Amps. Additionally, it has an interrupting rating of 25 kA at 50/60 Hz and a rated operational voltage of 240 Vac.

Working Principle

The IUGN1-1-52-5.00 employs a thermal magnetic protection system to provide over-current protection. This system works by detecting changes in the magnetic field around the breaker caused by excessive current and then tripping the breaker. Additionally, it uses an overvoltage protection system which utilizes a voltage-sensitive device to detect sustained periods of excessive voltage, at which point it triggers the breaker to shut off power.

In addition to providing over-current and overvoltage protection, the IUGN1-1-52-5.00 also offers under-voltage protection. This feature works by constantly monitoring the input voltage and then tripping the breaker if it falls below a set threshold.

The IUGN1-1-52-5.00 is a reliable, high-quality circuit breaker that is ideal for a range of applications. Its robust construction and wide range of features make it a premier choice for both residential and industrial use. It is UL 891 approved, offers thermal magnetic protection, undervoltage protection, and is rated for 400 amps normal current, 25 kA at 50/60 Hz and 240 Vac operations.
