Circuit breakers are devices that interrupt the flow of electricity in an electrical circuit when there is an overload of current or a short circuit. They are an essential component in any electrical system, and are designed to protect people and property from electrical damage. The IUGN6-1-65-20.0 is a particular type of circuit breaker which is designed to protect against overcurrent and short circuit conditions in a wide variety of applications, ranging from industrial and commercial installations to residential applications.

The IUGN6-1-65-20.0 circuit breaker is a three-pole, electronic tripping relay with a range of 0-20A. It is designed to provide electrical protection against short circuits, ground fault protection and overcurrent protection. The device features a current rating of 20A at 240V AC with a frequency range of 50/60Hz, and is UL and CSA approved. It is also suitable for direct-on-line motor starting with a separate starter current setting. In order to provide various levels of protection, the circuit breaker can be configured with a number of different trip curves.

The working principle of the IUGN6-1-65-20.0 is based on the well-established thermal magnetic trip principle. When the circuit breaker is in the open position, a small current flows through a heater coil and causes a thermal bimetal strip to expand. As the strip expands, it moves two electromagnets closer together, which allows a large current to flow through the electromagnets, thereby tripping the circuit breaker. This is the standard overcurrent protection feature. The IUGN6-1-65-20.0 also includes ground fault protection, which is activated when the current imbalance between the connected phases exceeds a predetermined threshold.

The IUGN6-1-65-20.0 is suitable for a variety of applications, including industrial control, commercial lighting, and residential load centers. They are also ideal for use in motor control circuits as a direct-on-line starter, with adjustable current setting to prevent overloads on the motor. Additionally, they can be used in low voltage switchboards and distribution boards where electromagnetic tripping is required.

In summary, the IUGN6-1-65-20.0 is a three-pole, electronic tripping relay designed to protect against short circuits, ground fault protection, and overcurrent protection in a range of applications. The device has a current rating of 20A at 240V AC, with a frequency range of 50/60Hz, and is UL and CSA approved. It is based on the thermo-magnetic trip principle and is suitable for direct-on-line motor starting, as well as industrial, commercial, and residential installations.
