Circuit breakers are essential components of electrical systems, and they can play a vital role in providing an efficient, reliable, and safe electrical infrastructure. The 8340-T110-K1M2-ALH126-3A is a circuit breaker manufactured by Siemens and is widely used in many applications. This article will discuss the application field and working principle of the 8340-T110-K1M2-ALH126-3A circuit breaker.

The 8340-T110-K1M2-ALH126-3A circuit breaker is designed for use in medium-voltage power systems. It is suitable for both indoor and outdoor applications, and is used in the protection of power plants and industrial installations. The breaker can be applied in radial, loop, and switching configurations for motor and non-motor control circuits. It is rated for up to 7000A, and can provide maximum short-circuit protection. It is also suitable for motor overload and short-circuit protection.

The working principle of the 8340-T110-K1M2-ALH126-3A circuit breaker is based on a thermal magnetic trip system. This system is a combination of the thermal overload and magnetic trip elements. The thermal overload element monitors the current in the circuit, and trips the breaker if it exceeds a predetermined level. The magnetic element is connected to the breaker itself and will trip if the current exceeds a predetermined level. This provides effective protection against both short-circuit and overload conditions.

The 8340-T110-K1M2-ALH126-3A also features an adjustable range of settings, allowing users to configure the breaker to their specific needs. The breaker also features a manual reset switch, which allows the user to manually reset the breaker in cases of emergency. This switch can also be used for testing the breaker before installation.

In conclusion, the 8340-T110-K1M2-ALH126-3A is a versatile circuit breaker that is used in many medium-voltage power applications. Its thermal magnetic trip system provides effective protection against short-circuit and overload conditions and its adjustable settings allow users to customize the breaker to their specific needs. Its manual reset switch is also a useful feature for testing and for resetting the breaker in cases of emergency.
