Circuit breakers are important components of the electrical system. They are used to protect the circuit from any potential damage caused by an overcurrent, short circuit or other fault. The IULHK21-35157-60 is an example of a circuit breaker designed for both commercial and industrial applications.

The IULHK21-35157-60 circuit breaker is a two-pole circuit breaker rated for 277/480 VAC and 80% rated continuous current. This means it can handle up to 35A of current. It has an adjustable trip and reset knob that can be adjusted based on the type of application the circuit breaker is being used for. It also comes with a double-pole switch that allows the circuit breaker to be switched between two different positions, making it a suitable choice for residential or light commercial applications as well.

The main working principle behind the IULHK21-35157-60 Circuit Breaker is its thermal-magnetic switching operation. This means it uses a combination of both thermal and magnetic properties. When a current passes through the circuit breaker or its contacts, a small portion of energy is released due to the resistance. This energy causes the circuit breaker to heat up and its thermal properties react to this. As the temperature of the circuit breaker increases, it trips and causes a current interruption.

The magnetic properties of the circuit breaker act on the contacts, creating a magnetic field. This field exerts force on the contacts when flow of current is detected, which in turn moves the contacts away from each other and causes an interruption in the circuit. The IULHK21-35157-60 circuit breaker is also equipped with an adjustable trip setting so that the amount of current will trigger the circuit breaker can be adjusted. This makes it suitable for a variety of applications, including residential and light commercial.

The IULHK21-35157-60 circuit breaker can also be used in DC applications as it comes with a red DC switch, which is used to override the magnetic and thermal action of the circuit breaker in DC applications. This allows the circuit breaker to turn off the DC current while still protecting the circuit from any overload or shorted circuit.

The IULHK21-35157-60 circuit breaker is a versatile and reliable electrical component that can be used in a variety of applications. It is easy to install and offers reliable protection against overcurrents or other faults. It can protect residential, light commercial, and industrial circuits from dangerous overloads or short circuiting. It is an important component of any electrical system and its efficient working principle makes it a valuable asset.
