9911400005

Circuit breakers serve two primary functions: they protect electrical circuits by preventing excessive current from flowing through them, and they disconnect electrical circuits when they become overloaded. The 9911400005 circuit breaker is a two-pole sub-circuit, breakers rated for 240VAC / 50A. As such, it is primarily used in medium and low voltage applications.

The 9911400005 is a thermally operated tabular circuit breaker. The basic working principle of the device is the temperature-sensitive operating mechanism of the thermal element. Whenever current passes through the breaker, some of it is converted to heat in the thermal elements. This heat causes the thermal element to expand, which in turn causes the contacts to move apart and open the circuit.

In addition to protecting against over-current, the 9911400005 also provides a level of protection against circuit overloads due to heat buildup from resistive loads. In the event of an overload, the thermal element will heat up and open the breaker.

In addition to the two-pole design, the 9911400005 are available in a single-pole version. The single pole circuit breaker is just a basic device with one contact, making it the ideal choice for low-voltage applications where protecting just one circuit is required.

The 9911400005 circuit breaker is also equipped with an adjustable trip setting. This feature allows the user to set the breaker trip point to a specific current value, which provides added protection against sudden increases in load.

The 9911400005 is a versatile, cost-effective circuit breaker that can be used in a wide variety of applications. It is suitable for use in residential, commercial and industrial applications, and is particularly well-suited for use in solar and wind power systems.
