Circuit Breakers

Circuit breakers are an essential part of any electrical system. They protect circuits from excessive current, preventing circuit overloads and system damage. IUGN666-1-42-15.0 is a circuit breaker specifically designed for residential and light-commercial applications.

Application Field of IUGN666-1-42-15.0

IUGN666-1-42-15.0 is typically used in residential and light commercial applications, typically for protecting branch circuits. It is rated for up to 15 amps of current and are available in single-pole and double-pole configurations. They are also suitable for both indoor and outdoor use.

IUGN666-1-42-15.0 breakers are designed to handle a wide variety of loads, including motors, lamps, lighting fixtures, HVAC equipment, and general-purpose circuits. They are also UL Listed and meet UL Standard 489 for residential and commercial applications.

Working Principle Of IUGN666-1-42-15.0

The working principle of the IUGN666-1-42-15.0 is quite simple. It contains two separate components: a bimetallic strip and a thermal-magnetic trip mechanism. The bimetallic strip is designed to react to changes in current. When current surpasses the circuit breaker’s rating, the strip is heated by the current and bends, triggering the thermal-magnetic trip mechanism and disconnecting the circuit.

The IUGN666-1-42-15.0 also features an adjustable trip mechanism which can be manually set to trip when the current is significantly higher than the breaker’s rating. This feature is designed to prevent system damage caused by surges or voltage transients. The trip settings also allow for customized applications such as protecting specific loads from over-current.

In addition, the IUGN666-1-42-15.0 features an internal lubricant which reduces wear and tear on the bimetallic strip, increasing the breaker’s lifespan and reducing the need for maintenance.

Conclusion

The IUGN666-1-42-15.0 is an ideal breaker for residential and light commercial applications. It is designed to protect circuits from over-currents and surges, and its adjustable trip mechanism allows for customized protection. Its internal lubricant also reduces wear and tear, extending its lifespan. It is UL Listed and meets UL Standard 489 for residential and commercial applications, making it an excellent choice for any electrical system.
