Circuit breakers are safety devices used in electrical wiring systems to protect equipment and people from dangerous electrical conditions. The IUGX121-28529-5 is a type of circuit breaker designed to protect against voltage surge and over-current conditions. It works using an internal circuit breaker element that trips when the current level exceeds a pre-set limit or when a voltage surge occurs.

The IUGX121-28529-5 is a three-pole circuit breaker with a rated voltage of 400V AC and a rated current of 63A. It is a two-stage circuit breaker with a current-limiting (CL) function and a voltage-limiting (VL) function. The CL function operates at a set current level and disconnects the power from the system in the event of an over-current condition. The VL function monitors the system voltage and disconnects the power in the event of a voltage surge.

The IUGX121-28529-5 is available in two different versions – a manual reset model and an automatic reset model. The manual reset model requires the user to manually reset the breaker after an over-current or voltage surge event. The automatic reset model automatically resets the breaker after the current or voltage levels have returned to normal. It also features an auxiliary contact that can be used to control other devices or to provide feedback when the breaker trips.

The IUGX121-28529-5 circuit breaker is designed for applications that require protection from over-current, under-voltage, or voltage surge conditions. It is suitable for use in both residential and commercial settings. It is particularly well-suited for use in motor control systems, where it can protect motors against over-current conditions and provide protection against damaging voltage surges.

The IUGX121-28529-5 is a reliable circuit breaker that is easy to install and maintain. It is robust and reliable, and it has been tested to withstand current surges up to 100A. It offers excellent protection against dangerous electrical conditions and is a cost-effective choice for many applications.
