229-2-71053-25 Circuit Protection

Circuit Breaker is an automated device that is used to protect an electrical circuit from damage due to overcurrent or short circuit. A circuit breaker is composed of two parts: the circuit breaker itself and the circuit breaker monitoring system. The circuit breaker monitors the current flowing through the circuit and will automatically disconnect the circuit should the current exceed a certain value. The 229-2-71053-25 circuit breaker is a popular choice for applications that require either non-parallel or multi-parallel operation. Its main features include a wide range of ratings, multiple contact configuration, and an innovative variable current overload protection system.

229-2-71053-25 Application Field

The 229-2-71053-25 circuit breaker is suitable for a variety of applications, including residential and industrial settings. It can be applied in AC circuits and DC circuits with ratings up to 150 kVAC with no more than 5,000 amp circuits. The 229-2-71053-25 circuit breaker is ideal for applications such as stand-alone protection for high-resistance motor loads, protection of high-voltage distribution networks, and protection of low-voltage transformers. The 229-2-71053-25 circuit breaker can also be used for voltage sensing applications, where the circuit breaker senses a voltage difference between two points and trips when the difference exceeds a certain set-point.

Working Principle

The 229-2-71053-25 circuit breaker uses a series of electromechanical components to sense the current flowing through the circuit and then trip when the current exceeds the pre-set limit. The current is measured by a series of binary encoded relays, which allow the circuit breaker to measure multiple currents simultaneously. The trip limit is adjustable via a dedicated rotary encoder and can be adjusted depending on the application. When the current exceeds the trip limit, the relays will automatically deactivate and trigger the trip switch.

In addition to the current sensing relays, the 229-2-71053-25 circuit breaker also features an innovative variable current overload protection system. This system allows the breaker to monitor the voltage and/or current of the circuit and trip in the presence of a very high current overload – even when the pre-set trip current has not been reached. This feature is particularly useful for preventing damage due to short circuits. In addition to overload protection, the 229-2-71053-25 circuit breaker also features reverse polarity protection and surge resistance.

Conclusion

The 229-2-71053-25 circuit breaker is a versatile circuit protection device with a range of features that make it ideal for a variety of applications. It offers reliable protection against overcurrents and short circuits, and its innovative variable current overload protection system is particularly useful for preventing damage due to short circuits. The 229-2-71053-25 circuit breaker is available in multiple contact configurations and can be applied in AC circuits and DC circuits with ratings up to 150 kVAC. It is suitable for residential, industrial, and voltage sensing applications.
