Circuit Breakers - 1278940000 Application Field and Working Principle

Circuit breakers are an important component of electrical equipment, and are widely used to prevent overload in various electrical systems. The 1278940000 circuit breaker is an advanced circuit breaker built on a rocker and hinge frame. It is designed to provide excellent operational durability, flexibility and reliability in a wide range of applications. This article will explain the application field and working principle of the 1278940000 circuit breaker.

Application field

The 1278940000 circuit breaker is used for medium- and high-voltage applications, ranging from 0.23kV to 24kV. It is a highly reliable device suited for a wide range of applications, including overcurrent protection, short-circuit protection, overload protection, and others in both industrial and residential applications. It is also used for motor protection in industrial settings, such as water and sewage treatment plants, agricultural applications, factories, and other industrial environments.

Working principle

The 1278940000 circuit breaker works by automatically disconnecting the circuit in the event of an overload or short circuit. This is done by the use of an internal trip unit, which detects any irregularities in the current and triggers the circuit breaker to open. When the trip unit detects an overload, it sends a signal to the circuit breaker, causing it to open and shut off the power in the circuit. This is done to protect the circuit from further damage. In the event of a short circuit, the trip unit will also send a signal to the circuit breaker, which will immediately open and shut off the power in the circuit.

The 1278940000 circuit breaker also comes with a manual reset feature. This feature allows for the switch to be reset manually in the event of an overload or short-circuit. This feature is especially useful when dealing with accidental trips. The manual reset switch is located on the exterior of the device, and can be reset with a button or a key.

Conclusion

The 1278940000 circuit breaker is a highly advanced device, designed to provide excellent operational durability, flexibility and reliability in a wide range of applications. It is used for medium and high voltage applications, and is designed to prevent overload and short circuit damage in electrical systems. It also features a manual reset switch which allows for the circuit breaker to be reset in the event of an accidental trip.
