Circuit breakers play an essential role in managing multiple sources of electrical energy in any power system.The CB255-30 is a type of circuit breaker that is used for low-voltage applications. In this article, we will discuss the application field and working principle of the CB255-30.

The most common applications for the CB255-30 are in panel board, switch gears, and switch boards. Such applications require a mechanical device to be activated to interrupt the current when necessary. The CB255-30 is a miniature, insulated case, circuit breaker that comes with a connection to mount on the standard TS-35/7.5 DIN rail. It is also equipped with a manual trip facility and a latching trip indicator.

The CB255-30 is able to smoothly and reliably switch loads under short-circuit and overload conditions. When it senses a short-circuit in the system, it can disconnect the faulted part of the system very quickly, thus protecting all downstream loads from damage, as well as providing a great level of safety.

The CB255-30 is an ideal device for controlling and managing systems that are exposed to large loads and currents over long periods of time. This circuit breaker will provide superior protection against short-circuits, overloads and overvoltages. Additionally, it helps maintain a stable power supply and can be used in medium and high voltage applications.

The CB255-30 circuit breaker works using a trip unit that provides overload and short-circuit protection. When the unit senses an overload or a short circuit in the system, it initiates a current tripping process. The current path from the source to the load is isolated by opening the contact gaps in the circuit breaker. Furthermore, the CB255-30 breaker is equipped with an adjustable thermal tripping time, which allows for the breaker to be adjusted for different time values, depending on what type of application it is being used for.

The CB255-30 circuit breaker also features a manual reset option. The manual reset allows the circuit breaker to be reset in the event of an overload or short circuit. Additionally, the CB255-30 breaker has a latching trip indicator, which indicates the status of the circuit breaker. The latching trip indicator is a feature that allows the device to remain in a safe operating condition.

In conclusion, the CB255-30 is a miniature, insulated-case circuit breaker designed for low-voltage applications. It is equipped with a trip unit that provide overload and short-circuit protection and has a manually reset option and a latching trip indicator. Thanks to its adjustable thermal tripping time, it is extremely reliable and an ideal device for controlling and managing systems that are exposed to large loads and currents over extended periods of time.
