Circuit Breakers are an important component in the electrical industry. They are used to prevent damage to equipment, circuits, and buildings, as well as providing easy repair of equipment. This article will discuss the 808-US0033-5A application field and working principle.

The 808-US0033-5A is a highly reliable, high-performance circuit breaker that is typically used in military, medical and industrial applications. This circuit breaker features a UL489 design, which incorporates special features designed to make it suitable for hazardous applications. It also features an adjustable temperature setting and an adjustable current rating.

The 808-US0033-5A is designed to protect circuits in the event of a short circuit or an overload. It is designed to detect any possible short circuit or over-current and trips in less than three milliseconds. When tripped, the breaker turns off the power supply and prevents further damage to the circuit. The trip delay can be changed from 0 to 15 milliseconds, depending on the application.

From the design point of view, the 808-US0033-5A uses a two-pole design for added safety. It is equipped with two contacts, one for power and the other for ground. This helps to ensure both flows in the circuit are interrupted if a short or overload occurs. It also helps to reduce the risk of fire if a short or overload occurs.

In terms of working principle, the 808-US0033-5A is equipped with a bimetal element. This element is responsible for detecting and reacting to temperature changes in the circuit. As the current flowing through the circuit rises, the temperature of the bimetal element increases, creating a potential difference between the two contacts of the element. This then triggers the trip mechanism and the breaker trips, shutting off the power supply and preventing further damage to the circuit.

The 808-US0033-5A is also equipped with a temperature setting that allows users to set the operating temperature of the circuit breaker. This helps to ensure that it will only trip at temperatures which are safe for the circuit and will not cause any damage to the equipment. Additionally, the breaker has an adjustable current rating that allows users to set the maximum current that it will carry.

In summary, the 808-US0033-5A is a highly reliable, high-performance circuit breaker designed to protect circuits in the event of a short circuit or an overload. Its design incorporates a UL489 rating, two-pole design, special features, adjustable temperature setting and adjustable current rating. Its working principle is based on the bimetal element, which reacts to changes in temperature and triggers the trip mechanism, shutting off the power supply and preventing further damage to the circuit.
