Circuit breakers are vital components used in electrical systems to protect them from damage due to overloads, short circuits or ground faults. The IUGH111-1-66F-20.0-01 is a circuit breaker designed for heavy-duty applications and capable of providing reliable protection against all types of electrical faults.

The IUGH111-1-66F-20.0-01 was designed specifically for use in medium voltage power systems where a high degree of protection is needed, such as in the power generation, transmission, and distribution industries. It is suitable for use with a wide range of current ratings, ranging from 200A to 6300A. It is incredibly robust and reliable, with a short-time rating of up to 20kA and fault interrupting ratings of up to 50kA.

The IUGH111-1-66F-20.0-01 has been designed with several features that make it suitable for its intended applications. It features a robust housing and is IP66 rated, so it is dust tight and protected against high-pressure water jets. It also has a wide voltage range and is suited for use in AC low- and medium-voltage networks from 20V up to 1000V.

The IUGH111-1-66F-20.0-01 also has a variety of safety features. It is equipped with trip-free mechanism that allows tripping without the need to reset before the breaker can be used again. This helps prevent dangerous errors from occurring. It also has a vacuum interrupter unit, which allows it to interrupt electric arcs rapidly and with a high level of reliability. Additionally, it has a range of manual and motor-operated operation modes, so it can be used in a variety of operating scenarios.

The IUGH111-1-66F-20.0-01 operates on the principle of thermal-magnetic protection. In this system, a thermostat senses the current flowing through the breaker at all times. If the current passes a certain threshold, the thermostat opens the main contacts. The magnetic action of the device also helps break the circuit by physically opening the contacts when the current reaches a certain value. This provides an additional layer of protection above and beyond the thermostat\'s action.

The IUGH111-1-66F-20.0-01 is an advanced device, allowing for faster and more reliable protection of vital components in medium voltage power systems. It has been designed with features that make it suitable for a wide range of applications, from power generation, transmission, and distribution to other commercial and industrial applications. Its thermal-magnetic protection system ensures that it can respond quickly and reliably to overcurrents, ground faults, or short circuits, protecting not just the device but the entire system.
