Circuit breakers are essential safety devices used in electrical systems to protect both people and equipment from the risk of a potentially dangerous electrical arc. The model code 9926251915 is a standard design and is used in a wide variety of applications. This article will discuss the model’s application field and working principle to help better inform decision makers.

Applications

The 9926251915 model circuit breaker can be found in many major industries including off-grid energy, home and commercial buildings, hospitals and medical facilities, factories, and even space exploration. These models are particularly valuable due to their ability to quickly and reliably break the flow of electricity, which can be critical during emergency situations. Additionally, they are designed to be able to withstand severe environmental conditions, and therefore are well-suited for outdoor applications. The 9926251915 model is also designed to be durable, lightweight, and easy to install and maintain, making it an attractive choice for many applications.

Working Principle

The 9926251915 model is a type of thermal circuit breaker that uses a combination of temperature and electrical current to protect electrical systems from damages caused by overcurrent. When the circuit is carrying more current than its rated limits, the current will cause the temperature of ambient air to rise and will create a temperature difference between the ambient air and the circuit breaker. This temperature difference is sensed by a temperature-sensitive bi-metal strip, which causes a mechanical spring to move and open the switch contacts. This action will break the electrical circuit, cutting off the current and interrupting the working of the system.

In addition to being able to sense high current levels, the 9926251915 model also provides protection against electrical arcs that are created during faults. When the contacts are opening, a spark will be generated, which will then cause an arc of electrical current to form. This arc is quickly extinguished by the combination of atmospheric air and the gas (nitrogen or sulfur hexafluoride) used in the circuit breaker’s interior. This process helps to prevent the switch contacts from being damaged due to heat produced by the arc.

Conclusion

The 9926251915 model circuit breaker is a reliable, lightweight, and easy to install and maintain solution for a variety of applications. Its ability to quickly and reliably break the flow of electricity makes it an attractive choice for many applications, and its ability to quickly break electrical arcs makes it especially beneficial for outdoor applications. Its combination of temperature and electrical current sensing makes it well suited for preventing failure in electrical systems.
