Circuit Breakers: IELR1-37875-10-V Application Field and Working Principle

Circuit breakers are essential components in any electrical system. They are designed to protect the electrical system by automatically disconnecting the circuit when excess current is present, preventing damage to the entirety of the system, and even fires. The IELR1-37875-10-V circuit breaker is a current limiting type designed to be used in low-voltage applications. This article will discuss the application field and working principle of this specific circuit breaker in particular.

Application Field

The IELR1-37875-10-V is designed to be used in low-voltage applications, such as lighting and HVAC controls. It was created for installations that don’t require additional overcurrent protection for the circuit. The IELR1-37875-10-V is equipped with a bimetal current limiter, which is designed to automatically react to the level of current present. This feature allows for the circuit breaker to shut down in the event of an overload or short circuit.

The IELR1-37875-10-V is a great choice for many other electrical applications. Its small size makes it perfect for tight spaces, such as residential fuse boxes. It is also capable of handling any standard voltage (24 to 127 VAC) with a power rating of 10 Amps. In addition, it meets UL 1077 safety rating standards. All of these features make the IELR1-37875-10-V an ideal choice for many different electrical applications.

Working Principle

The working principle of the IELR1-37875-10-V is based on a bimetal strip. This is a strip composed of two metals with different thermal expansion rates. When electricity flows through it, heat is generated and the strip bends in response. This triggers an internal switch that stops the flow of electricity.

In the event of an overload or short circuit, the current level will rise above the normal operating level. This excessive current then causes the bimetal strip to heat up and bend quickly. The internal switch will then respond by cutting off the flow of electricity, thus protecting the entire electrical system.

In addition to its bimetal strip, the IELR1-37875-10-V also contains a thermal-magnetic tripping mechanism. This mechanism measures both the heat and the current flowing through the bimetal strip. If both exceed the set limit, the switch inside the circuit breaker will be triggered and the current will be cut off automatically.

The IELR1-37875-10-V also has overload protection. This is a feature that prevents the circuit from becoming damaged due to excessive current draw. The circuit breaker will automatically shut down if the current draw exceeds the pre-set limit for a certain amount of time.

Conclusion

The IELR1-37875-10-V circuit breaker is a great choice for many low-voltage applications. It is equipped with a bimetal current limiter, a thermal-magnetic tripping mechanism, and overload protection. All of these features combine to make the IELR1-37875-10-V an ideal choice for protecting electrical systems from overload and short circuit situations.
