IEGZX21-29903-1-V Application Field and Working Principle

The IEGZX21-29903-1-V circuit breaker is mainly used in indu strial and commercial environments, such as in high-voltage power lines and electronic equipment and appliances. This type of circuit breaker is a three-phase contactor with a contact capacity of 440V AC that can withstand up to 50 times of the rated current or 100 times of the rated current during short circuit. It is equipped with a manual/automatic reset switch for enablin g control over the circuit breaker, and a quick-opening mechanism for effective interruption of the current in the event of an emergency.

The working principle of the IEGZX21-29903-1-V circuit breaker can be explained as follows. When the circuit breaker is installed, a bi-metallic strip is positioned inside it. The purpose of the bi-metallic strip is to detect an overload and cause the contact points to open. As the current in the circuit increases beyond the rated current, the bi-metallic strip bends and triggers the contact points to open. Since the IEGZX21-29903-1-V circuit breaker is equipped with quick-opening mechanisms, it can quickly react in an emergency situation and interrupt the current almost instantly. In addition, the manual/automatic reset switch enables the user to easily reset the circuit breaker without having to manually open and close the contact points.

In conclusion, the IEGZX21-29903-1-V circuit breaker is an essential component for safety and protection of circuits. It is designed to detect and protect from overloads, sudden power surges, and short-circuits, and it is equipped with quick-opening mechanisms and manual/automatic reset switch for user convenience. Overall, this type of circuit breaker is an important addition to any industrial and commercial environment.
