Circuit Breakers

A circuit breaker is an essential part of the electrical distribution system that is used to protect people against electric shock, equipment against fire, and electrical systems. The UPL11-5872-5 circuit breaker is a specific type of circuit breaker primarily designed to provide protection for electrical equipment against short circuit and overload currents.

Application Field for the UPL11-5872-5 Circuit Breaker

The UPL11-5872-5 circuit breaker is ideal for use in a variety of industrial and commercial applications. The circuit breaker is approved for DC and AC applications in industrial control, motor protection, and wiring protection, as well as analog signals and digital logic. The UPL11-5872-5 is suitable for use in applications such as industrial control, motor protection, and the protection of box-type controls and meters. It can also be used in AC and DC power systems.

Working Principle of the UPL11-5872-5 Circuit Breaker

The UPL11-5872-5 circuit breaker is a thermal-magnetic breaker that uses a combination of thermal energy produced by currents exceeding its rating, and magnetic energy produced by the current. When a fault occurs, the magnetic field around the breaker core will be disturbed by the current, which will cause the breaker to trip. The amount of heat that is generated by the fault current depends on the time period that the fault current is present, as well as the magnitude of the current. Once the temperature of the circuit breaker climbs to a specific level, tripping occurs regardless of the value of the fault current.

The UPL11-5872-5 circuit breaker contains a thermal release that senses temperature increases due to overloads and opens the circuit. The breaker has thermal and magnetic elements that can be adjusted, allowing the exact level of protection to be set depending on the application. To protect an electrical system, the thermal release of the breaker has to be set to the rated current of the system; any overloads above this rating will be detected by the breaker and trip will be initiated.

Nowadays, circuit breaker manufacturer is making more reliable and safer circuit breakers that offer increased levels of protection. The UPL11-5872-5 circuit breaker is one such example. This type of circuit breaker offers the advantages of improved flexibility and decreased size, making it ideal for a variety of applications.
