Circuit breakers are electrical devices designed to protect equipment and appliances from overheating and damage caused by overloading or short circuit. The 209-1-29890-20 circuit breaker is a light-duty branch circuit breaker with a current rating of 20A and a rated voltage of 120/240VAC. It is UL listed and CSA certified for safety and meets National Electrical Code(NEC) requirements for installed branch circuit protection.

The 209-1-29890-20 circuit breaker is a thermal-magnetic trip unit that uses both a bimetallic strip and an electromagnetic coil. The bimetallic strip is attached to a spring-loaded trigger. When the current passing through the circuit exceeds the rated value, the heat generated by the current causes the bimetallic strip to bend and the trigger is released and the circuit is broken. The electromagnetic coil is connected to an electromagnet that is activated when the current passing through the circuit exceeds the rated value. The electromagnet attracts the trigger and breaks the circuit, thus protecting the equipment and appliances connected to it.

The 209-1-29890-20 circuit breaker has a manual reset push button that enables it to be re-energized after a circuit overload or short-circuit. It also has a Test/Trip button that allows the breaker to be tested before re-energizing the circuit. It is designed with a quick-make, quick-break mechanism for immediate tripping and resetting of the breaker in an emergency. The 209-1-29890-20 circuit breaker can be used in residential and commercial applications, including air conditioning, heating and ventilation, refrigeration and food service equipment, laundry equipment, and motors. It is suitable for branch circuit protection in indoor and outdoor areas.

The 209-1-29890-20 circuit breaker is easy to install, and its versatile wiring configuration allows for easy integration into existing systems. Its compact size and low weight make it a cost-effective and practical solution for electrical system protection. The 209-1-29890-20 circuit breaker is designed to provide reliable protection to a variety of electrical equipment and appliances, saving them from damage and destruction caused by electrical overloads and short circuits.

In conclusion, the 209-1-29890-20 circuit breaker is a light-duty branch circuit breaker designed to provide reliable protection to electrical equipment and appliances in a variety of residential and commercial applications. It uses a thermal-magnetic trip unit with a bimetallic strip and an electromagnetic coil to break the circuit if the current passing through the circuit exceeds the rated value. It is easy to install and offers a cost-effective solution to electrical system protection.
