Circuit Breakers

Circuit breakers are essential components of electrical systems designed to protect equipment from damage when a fault occurs. There are many different kinds of circuit breakers available, each type suited to a specific application. IEGS66-36261-40-UV is a circuit breaker that is used in various fields and has various working principles.

IEGS66-36261-40-UV application field

The IEGS66-36261-40-UV circuit breaker is a type of low-voltage (LV), current-limiting, general purpose, three-phase circuit breaker designed for arc-flash and short-circuit protection in commercial and industrial applications. It is suitable for use in lighting and power systems, industrial machinery and equipment, as well as other LV applications. The IEGS66-36261-40-UV is certified for use in areas with explosive atmospheres.

Working principle of IEGS66-36261-40-UV

The IEGS66-36261-40-UV operates in two stages. First, when an overcurrent condition is detected, the breaker trips in less than 10 cycles (0.17 seconds) to protect the system from further damage. In the second stage, the breaker has a current-limiting capability which prevents the arcing that often causes fires or damage to equipment. This current-limiting feature reduces system downtime in the event of a short-circuit.

Additional features

The IEGS66-36261-40-UV comes with several additional safety features, such as an externally visible trip indication for verification of a successful trip, a graded thermal memory device for improved protection during motor overloads, a power failure protection function to ensure the breaker remains closed during power outages, and an optional automatic reclosing feature for pre-selected fault applications. This breaker also has an adjustable sensitivity setting for customizing the trip characteristics to specific application requirements.

Conclusion

The IEGS66-36261-40-UV is a general-purpose, low-voltage circuit breaker designed for use in commercial and industrial applications. Its current-limiting capability eliminates the need for additional components and provides arc-flash and short-circuit protection. Its additional features ensure reliable, safe, and consistent operation.
