Circuit Breakers: 104-PR3-0.3A Application Field and Working Principle

A circuit breaker is an electrical device designed to protect an electrical circuit from damage caused by excess current from an overload or short circuit. The 104-PR3-0.3A circuit breaker is an example of an electrical device used in a variety of applications, such as residential, commercial, and industrial installations.

Applications of 104-PR3-0.3A Circuit Breaker

The 104-PR3-0.3A circuit breaker is specifically designed for single-phase applications with a voltage of up to 600 V and a frequency of up to 60 Hz. This type of circuit breaker is commonly used in residential homes, industrial facilities, and commercial establishments. It is also found in medical and industrial equipment, machine tools, and X-ray machines.In residential homes, the 104-PR3-0.3A circuit breaker provides an economical and reliable solution to protect against electrical hazards such as electrical fires, shocks, and overloading. It helps to prevent excessive current from flowing through a particular circuit, thereby protecting the appliance and the home from the potential damages caused by an electrical overload or short circuit. This type of circuit breaker is also used in commercial establishments as it helps to protect expensive equipment from electrical overloads and other related hazards.

Working Principle of 104-PR3-0.3A Circuit Breaker

The 104-PR3-0.3A circuit breaker operates on the principle of thermal-magnetic tripping. This type of circuit breaker is designed with two separate thermal-magnetic tripping components.When the current in a particular circuit reaches a certain threshold, the thermal component of the circuit breaker trips, causing the contacts of the breaker to open. This inhibits any further current flow into the circuit. The thermal component is designed to dissipate the heat generated from the current overload, thereby allowing the thermal element to cool down before the breaker can reset.The magnetic component of the 104-PR3-0.3A circuit breaker also trips when the current reaches a certain level, in order to further protect the circuit from damage. This type of breaker is designed with a time delay mechanism in which the magnetic component will trip after a certain period of time. This time delay helps to ensure that transient overloads are not treated as permanent overloads, which may lead to unnecessary tripping of the breaker.

Advantages of 104-PR3-0.3A Circuit Breaker

The 104-PR3-0.3A circuit breaker provides an economical and reliable solution to protect electrical circuits against hazards such as electrical fires, shocks, and overloads. This type of circuit breaker is also highly energy efficient, as it only requires a small amount of energy to perform its operation. Additionally, its thermal-magnetic tripping mechanism helps to further protect the circuit from overloads and short circuits, making it an ideal choice for a variety of applications.
