IULNK211-40059-5

Circuit breakers are essential components in many types of electrical systems, and they are often found in domestic, commercial and industrial applications. The IULNK211-40059-5 is a particular type of circuit breaker, and it is typically used for low voltage and residential applications. This article will explain the application field and working principle of the IULNK211-40059-5 circuit breaker.

The IULNK211-40059-5 circuit breaker is a double-pole, double-throw (DPDT) device. This means that it can switch between two different output states depending on the current applied to it. It is suitable for low voltage operation, such as in residential applications with up to 600 Volts AC or 250 Volts DC. It has a rated operational current of 10 Amps and an interrupting rating of either 25,000 (240VAC) or 10,000 (125VAC) Amps.

In residential applications, the IULNK211-40059-5 circuit breaker is used to protect two or three-wire circuits with 120, 208, 277 or 480 Volt AC systems. It can also be used to provide overload and short-circuit protection for various types of equipment, such as air conditioners, motors, pumps and transformers. It is also suitable for installation in residential and commercial electrical cabinets.

The IULNK211-40059-5 circuit breaker works by detecting current flow. If the current exceeds the pre-set limit then the breaker will open. This helps to protect the circuit from damage by cutting off the power supply. In addition, the breaker will remain open until the overload or short circuit is cleared. The breaker will then automatically reset itself.

The IULNK211-40059-5 circuit breaker also has a choice of optional manual control. This includes the manual override switch which allows users to manually open or close the breaker. This feature is particularly useful for maintenance purposes, where the breaker needs to be manually opened or closed for performing maintenance work. There is also a reset switch which can be used to reset the breaker after a trip occurs. This is useful for situations where the user is not sure if the reason for tripping is due to overload or short-circuiting.

In summary, the IULNK211-40059-5 circuit breaker is a double-pole, double-throw device used for low voltage and residential applications. It provides overload and short-circuit protection and is suitable for installation in electrical cabinets. It can be manually opened or closed via the manual override switch, and also provides a reset switch for resetting the breaker after a trip occurs. The IULNK211-40059-5 is therefore a highly useful circuit breaker for a wide range of residential and commercial applications.
