Circuit breakers are electrical devices designed to protect electrical circuits from being damaged by overloading or short-circuiting. They sense the current in an electrical circuit and respond to a sudden surge of current by rapidly disconnecting the circuit. The IELR1-29976-8-V is a type of circuit breaker that is used in a variety of applications, and can be tailored to meet the specific needs of each. In this article, we will explore the application field and working principle of the IELR1-29976-8-V.

Application Field

The IELR1-29976-8-V is a miniature circuit breaker (MCB) designed for a wide range of uses, from residential and commercial applications to industrial and automotive applications. It has a wide operating range, from 6 to 63 A, and can handle electrical currents up to 25 kA (kiloamps). This makes the IELR1-29976-8-V an ideal choice for any application where protection from overloading and short-circuiting is needed. It is also UL approved for use in North America.

The IELR1-29976-8-V has several features that make it suitable for a variety of applications. It has a temperature compensation system, which ensures the breaker will respond correctly in varying temperatures. It also has a voltage compensation system, which ensures the breaker will respond correctly in alternating current systems. Additionally, it includes a multi-lever mechanism and spring-loaded automatic trip mechanism, providing additional protection in the case of an overload or short circuit.

The IELR1-29976-8-V comes in several different case and terminal styles, making it suitable for both surface mount and through-hole mounting. It is also suitable for both low and high frequency circuits, making it a great choice for any circuit with a large amount of switching. Finally, the breaker can be integrated into larger systems, providing an additional layer of protection for sensitive equipment.

Working Principle

The IELR1-29976-8-V works by controlling the flow of current in an electrical circuit. It has two sensing contacts that are designed to detect current. When the current passes through the contacts, the electromagnetic force triggers a switch which rapidly disconnects the circuit. The switch then remains in the off position until the current drops to a safe level. This allows for the circuit to be quickly and safely shut down in the event of an overload or short circuit.

The breaker also includes a thermal trip mechanism, which is designed to respond to abnormal temperatures. When the ambient temperature rises above a certain level, the breaker trips and disconnects the circuit. This prevents the circuit from becoming too hot and damaging sensitive components.

The IELR1-29976-8-V is a reliable, versatile circuit breaker that can be used in a variety of applications. Its wide operating range, temperature compensation system, and integrated safety features make it an ideal solution for any application where protection from overloading and short-circuiting is needed.
