IUGH11-1-66F-20.0-21

Circuit breakers are an important part of any electrical system, protecting against voltage surges, short circuits, and other electrical faults. The IUGH11-1-66F-20.0-21 circuit breaker is designed to protect against very high voltage and current spikes, as well as highly reliable overload protection. In this article, we will discuss the application field and working principle of the IUGH11-1-66F-20.0-21 circuit breaker.

The IUGH11-1-66F-20.0-21 circuit breaker is designed for use in industrial applications, such as large-scale equipment, motors, pump systems, and power systems. It is rated for continuous current up to 200A, and for short time duty cycles up to 1000A. It has a voltage range of up to 1000V AC. The IUGH11-1-66F-20.0-21 is also designed for use in hazardous locations, allowing it to be safely used even in highly flammable or combustible environments.

The pre-trip break time for the IUGH11-1-66F-20.0-21 circuit breaker is set to 25 milliseconds. This ensures that the breaker trips before high current levels have time to cause much damage to existing equipment or surrounding components. The open terminals on the breaker are designed to prevent arc flash or other sparking hazards. Additionally, the IUGH11-1-66F-20.0-21 is designed to comply with UL standards for safety and quality assurance.

The IUGH11-1-66F-20.0-21 circuit breaker works by monitoring the voltage and current levels on the load side of the circuit. When the current or voltage exceeds the pre-set trip point, the breaker will rapidly open the contacts, causing a current interruption and protecting the circuit and any downstream devices.

The operation of the IUGH11-1-66F-20.0-21 circuit breaker is controlled by a thermal-magnetic trip unit. This trip unit measures the current and temperature in the circuit, and tripping the breaker if the current or temperature reaches a level that could cause danger. Additionally, the breaker is equipped with a manual reset feature to allow the breaker to be reset when necessary.

In summary, the IUGH11-1-66F-20.0-21 is a high quality, heavy duty circuit breaker designed for use in industrial applications. It is rated for a voltage range of up to 1000V AC and for short time duty cycles up to 1000A. It is equipped with a thermal-magnetic trip unit that measures current and temperature in the circuit, tripping the breaker when necessary. Additionally, the breaker is designed with a manual reset function, allowing the user to reset the breaker in the event of a fault or overload. The IUGH11-1-66F-20.0-21 is UL rated, making it highly reliable and safe to use.
