Circuit Breakers

The UPGH68-31140-1 is a type of circuit breaker that is designed to protect electrical circuits from damage caused by excess current. It is a three-pole, AC rated circuit breaker with a current rating of up to 1600 amps and a voltage rating of 720 volts AC. It is UL listed and CCC certified and meets American National Standards Institute (ANSI) safety and reliability standards.

Application Field

The UPGH68-31140-1 is designed for use in residential, commercial, and industrial applications, such as HVAC, power distribution, and motor control. It is suitable for a wide variety of applications, including AC circuits up to a maximum of 720 volts, DC circuits up to a maximum of 600 volts, and motor control applications. It is also used as a circuit breaker in motor control centers, transformers, and panelboards.

Working Principle

The UPGH68-31140-1 is a thermal-magnetic circuit breaker, meaning it has two different mechanisms to protect the circuit: a thermal element and a magnetic element. When the current exceeds the rated current, the thermal element will trip first. If the current continues to increase, the magnetic element will then trip to prevent further damage due to overheating. The trip time is adjustable, allowing the user to set the circuit breaker to trip at a specific time. The circuit breaker can then be reset manually or automatically depending on the situation.

In addition to preventing damage due to current overload, the UPGH68-31140-1 also has other features to ensure reliable performance. It features an adjustable short-circuit signal level for improved coordination with other breakers, and its advanced design helps to provide optimal performance in temperature and humidity environments.

The UPGH68-31140-1 is a reliable and versatile circuit breaker that is designed for a variety of applications. Its ability to protect circuits from damage due to overcurrent makes it an ideal choice for both residential and commercial applications.
