EA1-B0-26-630-32E-CC

Circuit Breakers are an essential device for the safe operation of electrical circuits and systems. The EA1-B0-26-630-32E-CC is a tripping type circuit breaker that incorporates advanced features to ensure safe and convenient operation. This article will discuss the application field and working principle of the EA1-B0-26-630-32E-CC circuit breaker.

The EA1-B0-26-630-32E-CC circuit breaker is designed for the protection of high voltage electric circuits and systems. It can be used for the protection of power transmission systems, distribution systems, motor and generator control systems, lighting and other equipment protection systems. The built-in protection of the circuit breaker includes short-circuit and overload protections, to prevent damage to electric circuits in case of malfunction.

The working principle of the EA1-B0-26-630-32E-CC circuit breaker is based on a three-stage tripping system. The three stages are the pre-arcing (break-before-make) stage, the pre-arcing-additional stage, and the trip current interruption stage. The pre-arcing stage is activated when the pre-arcing current is higher than the standard current. This current increases gradually until the break-before-make signal is triggered and the breaker is opened. In the next stage, the pre-arcing-additional signal is activated when the current further increases. This signal triggers the breaker to trip. The trip current interruption stage is activated when the current reaches a predetermined value and the breaker trips. This prevents further rise in current and possible damage.

In addition, the EA1-B0-26-630-32E-CC circuit breaker is equipped with a temperature-sensitive element called the tripping unit. This unit will open the connection if the temperature of the circuit exceeds a specified level, thus preventing possible damage due to overheating. The circuit breaker also features an indicator that indicates the status of the circuit breaker and can be seen even in the dark.

Finally, the EA1-B0-26-630-32E-CC circuit breaker is also equipped with an emergency manual tripping device. This device will enable the manual trip of the circuit breaker in the event of an emergency or accident. This will ensure that the circuit is disconnected immediately, and will minimise the risk of further damage.

The EA1-B0-26-630-32E-CC is a high quality and reliable circuit breaker. Its advanced features make it an ideal choice for protection of high voltage electric circuits and systems. It is easy to install, and the manual tripping device provides additional safety.
