Circuit breakers are an important part of power systems and can be used to provide protection from short-circuit, overload, and other abnormal protective events. The APL11-2R-29457-1 is an industrial grade two-pole miniature circuit breaker which is designed to offer enhanced performance and reliability.

This circuit breaker is suited for both indoor and outdoor applications and provides protection for a wide range of applications including commercial, industrial, and residential. It is available in both single pole and two-pole models with a rated current range of 10-100A.

Application Field

The APL11-2R-29457-1 is ideal for a range of low-voltage applications. As it is equipped with a metal handle, it can be used as a manually operated main breaker for switchboards and control panels in commercial, industrial and residential settings. It provides protection against short-circuit, overload, or other abnormal disruptive events. It can also be used as an auxiliary main breaker in industrial control panels where an electronic trip unit (ETU) is required. The compact size of the APL11 makes it suitable for use in industrial enclosures, switchboards, and control panels.

Working Principle

The APL11-2R-29457-1 is a thermally operated circuit breaker which works on the principle of overload and short-circuit protection. It is equipped with a metal handle that monitors the current flowing through the breaker. If the current exceeds the rated current of the breaker, then the metal handle moves to the ‘on’ position. This in turn activates the thermal device present in the circuit breaker which then trips the circuit breaker. This allows the breaker to automatically disconnect the power supply, thus providing protection against overload and short-circuit.

In order to reset the breaker, the metal handle must be moved to the ‘off’ position. This allows the thermal device in the breaker to cool down and reset the circuit breaker. Additionally, the APL11 breaker has an adjustable tripping curve to ensure the appropriate level of protection for various types of loads.

Conclusion

The APL11-2R-29457-1 is a two-pole industrial-grade miniature circuit breaker that is ideal for low-voltage applications. It can be used as a manual main breaker for switchboards and control panels, or as an auxiliary main breaker in industrial control panels where an electronic trip unit is required. The breaker works on the principle of overload protection and can be reset by moving the metal handle to the ‘off’ position. The adjustable tripping curve allows for the appropriate level of protection for various types of loads.
