Circuit breakers are electrical devices used to protect electrical systems and components from damage caused by overloads, short circuits, and other abnormal conditions. They are the ultimate protection against electric shock or other power-based accidents, and are very important for home, office, and industrial applications. The PR21-2-.500A-XX-V circuit breaker is one such device, designed to meet the specific requirements of industrial and commercial applications.

The PR21-2-.500A-XX-V circuit breaker is a three-pole, high amperage, low voltage device. It has a nominal capacity of 500A, a rated current of 20kA, and a rated voltage of 250V AC. This breaker is suitable for the protection of large motor loads and commercial and industrial applications such as air conditioners, pumps, welding, and other heavy-duty equipment. It is also suitable for use in public places such as airports, office buildings, and stadiums.

The PR21-2-.500A-XX-V circuit breaker has an advanced modular trip unit design that allows for convenient wiring, testing, and maintenance. The breaker\'s trip unit accomodates a wide range of settings, including ground fault protection, overcurrent protection, phase-to-phase protection, phase-to-ground protection, phase-to-phase-to-ground protection, and so on. This allows users to customize the breaker\'s protection parameter according to their specific needs.

The PR21-2-.500A-XX-V circuit breaker uses thermal-magnetic technology, which means that when the current flow through a circuit exceeds the breaker\'s rating for a certain period of time, the breaker will trip, cutting off the current. During overloads and short circuits, the breaker will switch on a bimetal element, which can sense the increase in temperature due to the increased current. The bimetal element will then activate the internal switch which will switch off the circuit, thus protecting it from damage.

The PR21-2-.500A-XX-V circuit breaker is built with a robust and durable design, making it suitable for long-term outdoor use and harsh environments such as marine applications. It is UL-certified and has superior performance in terms of power, protection, endurance and stability. In addition, the breaker is also RoHS-compliant and CSA-certified, ensuring safety and long-term reliability.

The PR21-2-.500A-XX-V circuit breaker is an ideal choice for customers looking for reliable and safe protection for their circuits. It is designed to provide superior protection and performance, while being both cost-effective and easy to use. With its many features and benefits, the PR21-2-.500A-XX-V circuit breaker is an excellent choice for any industrial or commercial application.
