Circuit Breakers

Circuit breakers are an electrical device used to protect an electrical circuit from damage caused by an overload or short circuit. They are usually found in industrial, commercial, and residential applications. When an excessive current flows in the circuit, the breaker will trip and open the circuit, preventing any further damage. The IEG66-35571-1-V is one such circuit breaker.

IEG66-35571-1-V Application Field and Working Principle

The IEG66-35571-1-V is a high performance circuit breaker designed to provide reliable protection in a variety of environments and applications. It is suited for use in industrial, commercial, and residential settings. The IEG66-35571-1-V comes with a rated current of 40A, a maximum operating voltage of 600VAC, and a short circuit current rating of 250A. It is also UL certified and meets IEC/EN 60947-2 and UL 1053 standards.

The IEG66-35571-1-V is equipped with a bimetallic element, which is the main component used in the circuit breaker. The bimetallic element is composed of two different metals, such as copper and iron. When an overload in current or a short circuit occurs, the metals expand at different rates due to their different temperature coefficients of expansion. This expansion causes the bimetallic element to bend and trip the circuit breaker, thus cutting off the current flow and protecting the circuit.

The IEG66-35571-1-V also features a built-in delay function. This delay prevents the circuit breaker from automatically resetting during a mild overcurrent or short circuit. It gives the user time to investigate and reset the breaker manually, ensuring that the system is not damaged during the process.

The IEG66-35571-1-V also includes a reset actuator, which helps to reset the circuit breaker manually when the excess current has been eliminated. The actuator can be easily operated with finger pressure. Additionally, the actuator is designed to be dust-proof and shock-proof to ensure long-term reliability.

In summary, the IEG66-35571-1-V is an excellent choice for circuit protection in a variety of environments. It is ul-certified, meets IEC/EN 60947-2 and UL 1053 standards, and is equipped with a bimetallic element, a delay function, and a reset actuator. It provides reliable protection from overcurrent and short circuits, and is suitable for use in industrial, commercial, and residential settings.
