Circuit Breakers

A circuit breaker is a protective device that has the ability to break an electrical circuit to prevent damage to an electrical appliance or to protect against a short circuit. In short, it works as an automatic switch that trips when an electrical overload is detected.The PP21-2-20.0A-OB-V circuit breaker is a single-pole breaker which is commonly used for wiring in residential or light commercial circuits. As its name suggests, it can handle up to 20 amperes of current, meaning it can safely handle today’s standard 120 V residential loads.The PP21-2-20.0A-OB-V circuit breaker is designed to interrupt circuit overloads and provide protection against short circuits. It is designed to trip at a predetermined current level, typically 15 to 20 amperes. This is accomplished by using a thermal/magnetic trip mechanism which is incorporated into the breaker.The thermal/magnetic trip mechanism works by utilizing the heat generated in the wire by the current overload and a bi-metallic strip. As the current overloads the circuit, it causes the bi-metallic strip to bend and act to trip the internal switch. The interaction between the heat and the bi-metal strip is what trips the circuit breaker.Since the PP21-2-20.0A-OB-V has a maximum rating of 20 amperes, it can be used in many different applications. It can be used in a variety of residential applications, including wall outlets, lights, heating and cooling systems, water heaters, and other electrical appliances. It can also be used in light commercial applications such as commercial kitchens, office buildings, and industrial settings.Although the PP21-2-20.0A-OB-V circuit breaker is designed to protect against electrical overloads and short circuits, it is important to note that it does not protect against high voltage surges or lightning-induced power surges. For protection against surges, a surge protection device must be used.In conclusion, the PP21-2-20.0A-OB-V circuit breaker is a single-pole breaker that can handle up to 20 amperes of current, making it suitable for residential and light commercial applications. Its thermal/magnetic trip mechanism helps protect against electrical overloads and short circuits. However, it does not provide protection against high voltage surges or lightning-induced power surges, so a surge protection device should be used for added protection.
