Circuit breakers are crucial pieces of equipment used in electrical systems and are designed to protect it from potential overloads. In the event that an overload is detected, the circuit breaker trips and isolates a short circuit or an overload from the power source. The 9926251003 circuit breaker is a popular choice in the industry due to its safety features and ability to improve system reliability. This article takes a closer look at the application field and working principle of the 9926251003 circuit breaker.

Application Field

The 9926251003 circuit breaker is a single phase AC (alternating current) breaker that is suitable for indoor and outdoor usage. It is commonly used in the electrical supply network of low voltage (400 V) and is particularly suitable for motor overload protection.

It is suitable for use in systems such as air conditioning, lighting, power supply systems, distribution systems, and short-circuit protection. The 9926251003 also supports the installation of auxiliary contacts and a monitaried contact, making it ideal for use in automation or remote control systems.

Working Principle

The 9926251003 circuit breaker is designed with a bimetal element that functions as the main component responsible for tripping the circuit when an overload or short-circuit occur. When a current greater than or equal to the rated current flows through the bimetal element, it will expand and cause the trip lever linked to it to pivot and actuate the trip mechanism.

The 9926251003 features an adjustable overload trip and a thermal manual reset function. This means that the system can detect a prolonged overload and trip automatically. Additionally, it also has temperature compensation meaning it can detect a small overload than usual which is beyond the normal working capability of a normal circuit breaker.

Conclusion

The 9926251003 is one of the most reliable circuit breakers on the market due to its safety features and capabilities. It’s suitable for use in many applications including air conditioning, lighting, power supply systems, and short-circuit protection. It has a bimetal element that can detect overcurrents, an adjustable overload trip, and temperature compensation. All of these elements ensure that the 9926251003 provides reliable and robust protection.
