A circuit breaker is a device designed to protect an electrical circuit from damage caused by overload or short circuit. Circuit breakers are usually rated by the maximum amount of current they can carry, and come in a variety of sizes and designs to suit different applications. One such circuit breaker is the 2C20UL, designed primarily for residential and commercial applications.

The 2C20UL is a double pole, UL 489 listed circuit breaker that provides overload protection of up to 120 volts circuits up to 20 amps. It features a reliable pressure-trip mechanism, with a snap-action switch and thermal-magnetic operation. It is equipped with a test button to verify circuit breaker operation, and it can be used as a replaceable device in either single or multi-pole applications.

Working Principle

The 2C20UL circuit breaker works on the principle of thermal-magnetic operation, which means that when a short or overload occurs, the flow of electricity causes the circuit breaker trip mechanism to increase the temperature of a wire coil, which in turn causes a magnet inside the unit to repel and open the switch contacts.

The snap-action switch contained within the unit is designed to provide fast operation, quickly opening and closing the circuit in response to any one of the following: an overload, a short circuit, or even a power surge.

The device is equipped with a manual trip button which allows a user to interrupt the normal functioning of the circuit in order to perform outside tests or to comply with safety requirements. When pressed, this button causes the circuit breaker to trip and interrupt the current.

Applications

The 2C20UL is designed for residential and commercial applications such as 120-volt lighting, heating, air conditioning, and appliances. It can also be used in multi-pole installations, in RV parks and campgrounds, and various industrial and other commercial settings.

It is important to note that while the 2C20UL is UL 489 listed, it is only suitable for use with 120-volt circuits. For any other application, a different type of circuit breaker is necessary.

The 2C20UL circuit breaker is designed to ensure the safety of electrical systems in residential and commercial environments. With its reliable pressure-trip mechanism and thermal-magnetic operation, the device is able to provide overload protection of up to 120 volt circuits in a fast and efficient manner.
