A circuit breaker is an important electrical device used to prevent circuits from overheating and becoming an electrical hazard. In a circuit breaker, the main purpose is to open or close a circuit, usually when an overload or short circuit fault has occurred. The IUGX66-20905-1 circuit breaker is a 3P enclosure type industrial circuit breaker, ideal for use with 3-pole electrical systems. It is designed to be used with thermomagnetic actuation and can be used in a variety of applications such as domestic, commercial and industrial applications.

The IUGX66-20905-1 circuit breaker utilizes thermomagnetic actuation which works by utilizing a combination of current sensing and thermally-induced actuation. This combination allows the circuit breaker to detect faults and open the circuit in order to prevent damage. The current sensing component of the IUGX66-20905-1 circuit breaker is a combination of an electro-magnetic release switch and a thermal bimetallic strip. The electro-magnetic release switch senses the current in the circuit and signals the thermal bimetallic strip to open the circuit by triggering the mechanical latch mechanism.

Once the magnetic switch senses the current, it signals the thermal bimetallic strip to actuate. The thermal bimetallic strip is composed of two different metals which will expand or contract depending on the temperature change caused by the current. When the current in the circuit exceeds the set threshold, the thermal bimetallic strip expands and activates the mechanical latch mechanism to open the circuit. This helps to prevent damage due to overloading and short circuiting, and will also protect personnel from electrical hazards.

The IUGX66-20905-1 circuit breaker is available in a variety of different ratings, such as 25, 50, 80, 100, 125, and 200A. This makes it an ideal choice for use in a variety of applications, including domestic, commercial and industrial applications. In addition, the circuit breaker has a robust construction and is designed to withstand a wide range of temperatures and adverse environments. It is also designed to meet strict safety requirements, such as IEC 60947-1 and NEMA standards.
