Circuit breakers offer a vital protective layer in electrical control and distribution systems. Without them, much of the equipment and the networks that it controls would be vulnerable to dangerous voltage and current levels, even in normal operation. The IUGBX11-32036-4R5 is a particularly useful circuit breaker that is widely used in many applications for its flexibility and durability. This article will explore its application field and working principle.

Application Field

The IUGBX11-32036-4R5 is a miniature circuit breaker (MCB) specifically designed for overload protection in low-voltage distribution networks. It is rated at 125A and designed to trip at 1.05 times its rated current, with a rated operating voltage of 240V. Due to its combination of current-sensing technology and compact size, the IUGBX11-32036-4R5 is widely used in a variety of industrial, commercial, and residential applications.

Its small size makes it ideal for space-constrained applications such as distribution boards, junction boxes, and lighting distribution circuits. In process industries such as food and beverage production, the IUGBX11-32036-4R5 can be used in pumps, motors, and other equipment to provide robust and reliable protection from overload. In residential applications, the IUGBX11-32036-4R5 is often used in energy-efficient homes to reduce energy consumption.

Working Principle

The IUGBX11-32036-4R5 operates by sensing the current flowing through the circuit and trips when it exceeds the rated current. It does this using a thermal-magnetic construction, which is composed of two separate parts. The first is a thermal component, which consists of a bimetallic strip that bends and breaks the circuit when the current passing through it becomes too high. The second component is a magnetic component, which consists of two precision-wound coils and a powerful permanent magnet.

The rapidly increasing current induces a magnetic field in the coils, which in turn creates a repulsive force between the coils and the magnet, pulling the handle and tripping the circuit. The Magnetic component of the IUGBX11-32036-4R5 is designed to trip the breaker within 0.2 seconds, meaning the circuit is opened faster than the current can cause significant damage.

In addition to their speed and precision, the IUGBX11-32036-4R5 circuit breakers have several other advantages, including robust construction and isolated contacts. The robust construction provides greater resistance to damage from vibration and shock, while the isolated contacts provide additional protection by separating the active and neutral connections, thus reducing the risk of electric shock in the event of an overload or fault.

Conclusion

The IUGBX11-32036-4R5 miniature circuit breaker is suitable for many applications due to its combination of current-sensing technology, robust construction, and small size. Its thermal-magnetic construction ensures fast and reliable protection from overload, while its isolated contacts provide protection against electric shocks. With its versatility and reliability, the IUGBX11-32036-4R5 has become a popular choice for many industrial, commercial, and residential applications.
