Circuit breakers are essential components in any power system. Their function is to protect the system from overcurrent and other faults. One of the most common types of circuit breakers is the UPL11-34178-30.

The UPL11-34178-30 is an oil-immersed, three pole, air-magnetic type circuit-breaker. This type of breaker is typically found in power distribution systems in industrial applications. It is a reliable and cost-effective solution for a range of applications.

The UPL11-34178-30 is a middle-voltage breaker. It is designed to work in networks from 12kV to 24kV. The breaker is available in ratings from 2700A to 13800A and it is equipped with three separate and independent, stab-coordinated arc chambers..

The working principle behind this circuit breaker is that it utilizes an induction magnetic field and air gap to protect the system from overcurrent and other faults. When a fault occurs, the magnetic field triggers the breaker\'s trip unit, which triggers the breaker to open. The air gap ensures that the magnetic field is kept away from the electrical contacts, thus limiting the damage of the contacts by preventing a spark in the event of a fault.

The UPL11-34178-30 circuit breaker has several safety features that ensure it operates properly. One of these features is the Temperature Control System. This system helps to protect the breaker from damage due to overheating. It is equipped with an automatic temperature monitoring device that ensures the temperature does not exceed a pre-set value.

The UPL11-34178-30 is a reliable, cost-effective, and safe solution to protecting power distribution systems in industrial applications. Its induction magnetic field and air-gap ensure that the contacts remain safe in the event of a fault. Its safety features, such as the Temperature Control System, ensure that it operates properly. The breaker is available in ratings from 2700A to 13800A, and is suitable for networks from 12kV to 24kV.
