Circuit Breakers

IUGF6-1-72-40.0-A-01 application field and working principle

Circuit breakers are among the most common electrical components used in devices ranging from fuse boxes to drones. One of the most popular of these breakers is the IUGF6-1-72-40.0-A-01, which is widely used in industrial, commercial, and residential applications. This article provides an overview of the IUGF6-1-72-40.0-A-01 circuit breaker, its application field, and its working principle.The IUGF6-1-72-40.0-A-01 is a type of molded-case circuit breaker (MCCB). It is a three-pole breaker that supports interrupt ratings of 40.0 A and ultimate short circuit breaking capacities up to 42kA. It can also accommodate overloads up to 180A. It is designed with a thermal-magnetic release, which combines both thermal and magnetic tripping mechanisms to detect and respond to overloads and short circuits.The primary application field of the IUGF6-1-72-40.0-A-01 circuit breaker is in industrial buildings, commercial properties, and residential homes. This breaker is best suited to applications with a low to medium risk of a short circuit or overload. It is not suitable for high-risk applications or hazardous locations, such as those found in oil rigs or chemical plants.The IUGF6-1-72-40.0-A-01 circuit breaker’s working principle is based on thermal, magnetic, and mechanical principles. This breaker is designed to detect both overload and short circuit conditions, and is particularly effective at detecting and responding to slow overloads. The thermal portion of the mechanism works by detect the temperature of the electrical circuit. When the temperature rises above a predetermined threshold, either from an overload or a short circuit, the bimetallic element will heat up and expand, releasing the breaker’s latches and tripping the circuit. The magnetic portion of the mechanism is based on an electromagnet. When an overload or short circuit is detected, the magnetic field generated by the electromagnet will be strong enough to pull the breaker’s contacts apart and trip the circuit.The mechanical portion of the mechanism is based on a spring-loaded latch. It is composed of a pivoting arm that is pushed away by the expanding bimetallic element or pulled away by the electromagnetic force. This triggers the latch to release, tripping the breaker and disconnecting the circuit.In conclusion, the IUGF6-1-72-40.0-A-01 circuit breaker is a highly effective and reliable breaker that is ideal for applications with a low to medium risk of short circuit or overload conditions. It is composed of three distinct mechanisms—thermal, magnetic, and mechanical—that work together to detect and respond to these conditions.
