Circuit Breakers

The UPGH111-1REC2-2919-21 circuit breaker is a great addition to any environment that requires an overload protection system. This particular breaker is designed for use with high voltage (615 volts and up) DC circuits, and also in applications where a circuit breaker can provide more efficient protection than a fuse. The design of this breaker includes an over-voltage disconnection feature, which can be used to protect the system from a sudden overload.

The UPGH111-1REC2-2919-21 circuit breaker consists of a specially designed device that is equipped with a switch, contacts, and a spring-loaded plunger. The switch is located inside the breaker, and is responsible for opening and closing the contacts. This is accomplished by alternately increasing and decreasing the pressure on the plunger. The spring-loaded plunger ensures that the pressure necessary to open or close the contacts is always the same, regardless of the current flow in the circuit.

When a circuit is being overloaded, the pressure on the plunger increases to the point that is greater than the pressure required to keep the contacts closed. As a result, the switch in the breaker will open, which will break the connection between the contacts and cause the circuit to be disconnected from the rest of the system. Once the overload condition has been remedied, the breaker can be reset by operating the switch.

The operation of UPGH111-1REC2-2919-21 circuit breakers is not only beneficial in over-current protection, but it can also act as a fail-safe device as well. In the event that the breaker fails to open, an additional safety device can be used to disconnect the circuit. This is usually done by using an external disconnect switch or fuse.

A further advantage of using UPGH111-1REC2-2919-21 circuit breakers is that they are equipped with an adjustable trip time feature. This allows the engineer or operator to make sure that the breaker trips at the appropriate time in order to protect the circuit. By adjusting the trip time, the system can be operated safely and efficiently without any unexpected power outages.

In addition to the over-voltage protection, UPGH111-1REC2-2919-21 circuit breakers also offer the advantages of a trip class rating system. This rating system is based on the volt-ampere rating of each circuit and is used to determine the amount of current each circuit should be able to handle. The higher the trip class rating, the more current the circuit can support.

UPGH111-1REC2-2919-21 circuit breakers are an ideal choice for a wide range of applications, from high-powered systems to smaller low-voltage applications. The adjustable trip time feature and the trip class rating system make them an excellent choice for providing safety and efficient power protection in any environment.
