Circuit breakers are devices used to protect electrical systems, such as those found in homes, businesses, and factories. They are designed to trip or shut off the power supply to a circuit in the event of an overload or short circuit. The IUGN66-33968-20 is a type of circuit breaker specifically designed for applications such as air conditioning, heat pumps, and refrigeration. The IUGN66-33968-20 is a single-pole, thermal-magnetic circuit breaker with a current rating of 30A. It features an adjustable trip setting, so it can be set to trip at a predetermined overload current. This makes it ideal for applications where precise control of power is required. The breaker also features a manual test button, which allows you to safely check the operation of the breaker without having to trip the circuit.The working principle of the IUGN66-33968-20 circuit breaker relies on two different types of protection. The first is thermal protection, which is provided by the use of a bimetal strip. The strip will bend in response to changes in temperature due to increased current flowing through the breaker. This bending will cause the breaker to trip and shut off the power supply to the circuit in the event of an overload. The second type of protection is magnetic protection, which is provided by the use of a magnetic coil. The coil will act as a sensor to detect changes in the current flowing through the breaker. When an overload occurs, the magnetic field will build up in the coil, resulting in the actuation of a trip mechanism. This trip mechanism will cause the breaker to trip and shut off the power supply to the circuit in the event of an overload.The IUGN66-33968-20 is a reliable and safe device to use in applications such as air conditioning, heat pumps, and refrigeration. Its adjustable trip setting allows for reliable protection against overloads. Its manual test button also makes it easy and safe to test the operation of the breaker without having to trip the circuit.
