Circuit Breakers

Circuit breakers are a type of electrical safety device designed to protect circuits from being damaged by excessive current. The 219-2-31977-1 is an industrial-grade circuit breaker designed to provide reliable protection in heavy industrial and commercial environments. This circuit breaker is designed to disconnect a circuit when it senses an overload or short circuit. In addition, the circuit breaker can be manually reset.

Application Field

The 219-2-31977-1 is designed for use in heavy industrial and commercial applications. Some of the more common applications are switchgear and motor control centers, distribution panels, motor starters, panelboards, and hvac systems. Because the 219-2-31977-1 is UL rated, it can also be used in critical applications such as elevators, fire protection systems, cranes, and other applications where safety is of paramount importance.

Working Principle

The that works on a bimetallic strip principle, sufficient current in the circuit will cause the bimetallic strip to heat up, bending the strip into an arc. This de-energizes the circuit until the overload is removed and the bimetallic strip cools down, re-energizing the circuit. The advantage of a circuit breaker is that it can sense a short circuit or an overload and respond quickly, allowing for fast circuit protection and increased safety. Additionally, circuit breakers can be manually reset, allowing for the circuit to be re-energized without having to replace the device.

Other Features

The 219-2-31977-1 features a quick-make, quick-break mechanism which helps ensure a fast and secure connection and disconnection. Additionally, this circuit breaker has a Service Entrance rating, meaning that it conforms to the highest standards set out by the UL, ensuring that it is suitable even for the most sensitive of applications. The circuit breaker is also designed to protect against invisible arc-fauls by carefully controlling the arc that forms between the contacts when they are opened.

Conclusion

The 219-2-31977-1 is a UL-approved industrial-grade circuit breaker designed to provide reliable protection in heavy industrial and commercial applications. It works on a bimetallic strip principle and is designed to quickly sense an overload or a short circuit and disconnect the circuit. This circuit breaker also features a Service Entrance rating and is equipped with a quick-make, quick-break mechanism, making it suitable for even the most critical of applications.
