Circuit breakers are frequently used in the industrial and commercial markets to protect electrical systems against overload and short circuit. They are designed to automatically disconnect electricity when excessively high levels of current flow through an electrical circuit in order to prevent damage to connected equipment. There are many different types of circuit breakers on the market, each designed to meet particular requirements of specific applications. One of the more commonly used types of industrial circuit breakers is the IEG1-31322-5.

The IEG1-31322-5 is a three pole, 15-20 amp circuit breaker that is UL 489 listed for industrial applications. It is suitable for disconnecting and protecting both single phase and three phase loads, and features a thermal magnetic trip unit. It is available as a standard-interrupting only version, or can be equipped with a ground-fault trip unit for personnel protection. The IEG1-31322-5 is rated for AC circuits up to 690V, with a rated operating temperature of -40 to 55 degrees Celsius.

The IEG1-31322-5 circuit breaker has an adjustable trip range designed to protect the connected load from overload and short circuit. The trip settings are adjustable, allowing the user to change the trip range to match the load characteristics. This feature allows the breaker to be used in a variety of settings, including motor control, ARTC and adjustablespeed drives, and critical power systems.

The working principle of the IEG1-31322-5 is relatively simple. Whenever current levels exceed the adjustable trip settings, a thermal element within the breaker is activated. This thermal element heats up and to the point where it is forced to open an internal contact, thus disconnecting the load from the power source. The breaker then automatically resets when the current levels fall below the adjustable trip setting. This resetting process substantially reduces downtime and the cost associated with manual resetting.

The IEG1-31322-5 circuit breaker is an ideal choice for industrial applications where reliable short-circuit and overload protection is required such as motor control, ARTC and adjusting speed drive systems and welders. Its adjustable trip settings, as well as its UL 489 listing and high voltage capability, make it a great solution for applications where performance, function and reliability are paramount.
