Circuit Breakers

Circuit breakers are essential components of an electrical system. As a type of switching device, circuit breakers are used to protect the electrical power system from overloads, short circuits, and voltage surges. The IEGZXF6-35906-388-V is a miniature circuit breaker (MCB) designed for AC circuit applications.

Application Field

The IEGZXF6-35906-388-V MCB is designed to protect residential or commercial buildings, industrial facilities, and other electrical circuits against overloads, short circuits, and voltage surges. It is suitable for a wide range of applications, including home appliances, lighting systems, HVAC systems, and pumps. The MCB has a wide operating temperature range of -20°C to +60°C, allowing it to be used in a variety of locations. The IEGZXF6-35906-388-V can be used in a single pole or double pole configuration, making it suitable for a variety of power distribution systems.

Working Principle

The IEGZXF6-35906-388-V MCB is an electromechanical device that operates on the principle of overcurrent protection. The MCB contains an electromagnet, which is connected to the trip lever. The MCB also contains a bi-metallic strip, which is connected to the trip lever. When a sudden overload current passes through the MCB, the electromagnet will activate, causing the bi-metallic strip to expand. This will cause the trip lever to move and the MCB to switch off, thus protecting the circuit. In addition, the MCB also contains a thermal element, which is designed to detect and protect against slow increases in current. If the sensed current exceeds the pre-set trip points, the thermal element will heat up and activate the trip lever, causing the MCB to switch off.

The IEGZXF6-35906-388-V MCB also contains an adjustable overload protection, which allows for further control in circuit protection. This feature can be used to prevent an overload condition by allowing the user to adjust the tripping current of the MCB, allowing for greater flexibility in the design of electrical systems. The adjustable overload protection also allows the user to determine the amount of current that is needed to start the MCB.
