Circuit breakers are lifesavers, designed to protect the electrical components of a building from harm due to overcurrent or short-circuits. They are an essential component of any electricity system, and are often the difference between safety and danger. UPL1-2238-7 is a type of circuit breaker, and widely used in a variety of applications. In this article, we’ll take a look at the application field and working principle of UPL1-2238-7.

The UPL1-2238-7 is a UL489 approved miniature circuit breaker. It is designed to be used in residential, commercial, and industrial markets. It has a current rating of 10 amps and a voltage rating of 120/240 volts. It can protect 30-volt circuits from potential dangers like short-circuits and overloads. It can also be used in conjunction with other circuit breakers to protect higher voltage circuits.

UPL1-2238-7 is a thermal-magnetic circuit breaker. It operates based on three fundamental principles: heat, magnetic force, and mechanical action. Heat sensing components detect abnormal temperature increase in the circuit breaker caused by an overcurrent in the circuit, which then triggers the main contacts to open. The circuit breaker also has a magnetic force element, which provides an additional layer of protection. It is triggered by strong magnetic forces generated by an excess current that passes through the main contacts, which then deflects a metal component that is connected to the contacts, causing them to open.

Finally, the circuit breaker has a mechanical action component. This component is triggered when the contacts are unable to close during an overload, due to the high mechanical and thermal forces created by the current. When this occurs, the mechanical action element will move to open the contacts, protecting the circuit from harm.

UPL1-2238-7 is a highly reliable circuit breaker, and its unique combination of thermal, magnetic, and mechanical action provide superior protection. It is specifically designed for residential, commercial, and industrial applications, and its UL489 approval makes it an ideal choice for any circuit where safety is a concern. It is easy to install and maintain, and its compact size allows it to fit into tight spaces. Overall, the UPL1-2238-7 is an impressive circuit breaker, providing superior protection and immense reliability.
