Circuit Breakers

Circuit breakers are key components of electrical systems that protect against overcurrent. They are designed to trip and shut off current flow when an abnormally high current is detected. The IEGH666-33400-20-V is an example of a circuit breaker that fulfills this important task, specifically designed for residential applications.

Application Field

The IEGH666-33400-20-V circuit breaker is a one-pole molded case circuit breaker with a voltage rating of 240VAC. Its short-circuit rating is 10,000A. This makes it ideal for residential applications, protecting areas like kitchens, bathrooms, and laundry rooms. It is also frequently used in home laboratories to guard against higher current—potential short-circuit conditions. Furthermore, it can also be used in the protection of small motor circuits, such as those of pumps, air conditioners, and refrigerators.

Working Principle

The working principle of a circuit breaker, such as the IEGH666-33400-20-V, is simple. It consists of an electromagnet with a contacts connected to it. When the current running through the circuit gets too high, the electromagnet gets energized and trips the contacts, interrupting the power supply to the circuit. The circuit breaker can then be reset, allowing the power supply to be restored.

Advantages

The primary advantage of the IEGH666-33400-20-V circuit breaker is its affordability. Considering the safety benefits it provides, it is an excellent value. It is easy to install, with a no-position plug-in connection. Its one-pole design is also simple and straightforward.

The IEGH666-33400-20-V is also approved by the Underwriters Laboratories, UL 489. This is important in areas with strict safety protocols, ensuring that the circuit breaker meets all the required standards. Furthermore, it also meets all of the requirements of the Canadian Electrical Code Part 1 / 21 (CECP) as well as the International Electrotechnical Commission (IEC) 60898.

Conclusion

The IEGH666-33400-20-V circuit breaker is designed specifically for residential applications, protecting against potential overcurrents and short-circuits. Its UL 489 approval and one-pole design make it the perfect choice for areas like kitchens and bathrooms, providing superior protection for those areas. It is also very affordable, with an excellent price-to-performance ratio. Overall, the IEGH666-33400-20-V is a great choice for residential circuit breaker applications.
