Introduction to 104-PR-3.5A Circuits Breakers

104-PR-3.5A is a type of circuit breaker, which is used to prevent damage to smaller circuits caused by electrical overload. A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. It works by opening the circuit and disconnecting the load when it trips due to an overload or a fault condition.

Application Field of 104-PR-3.5A Circuits Breakers

104-PR-3.5A circuits breakers are primarily used in safety-critical applications such as home and industry. They are designed to provide circuit protection from short circuits and overloads, and may also provide a degree of isolation between different circuits. In residential applications, 104-PR-3.5A breakers are used in the main electrical panel to protect against power surges and blackouts, as well as preventing household appliances and electronic equipment from being damaged due to an overload. In industrial settings, these breakers are used to protect industrial equipment, such as pumps, motors and hoists, from damage due to overload or short circuit.

Working Principle of 104-PR-3.5A Circuits Breakers

The working principal of 104-PR-3.5A circuit breaker is based on thermal-magnetic tripping mechanism. The circuit breaker consists of two elements: an electrically operated thermal element, which senses current passing through the circuit, and a mechanically operated magnetic element, which acts to trip the breaker when the thermal element is activated. The thermal element comprises a bimetallic strip, which is heated by the electrical current passing through the circuit. When this strip becomes too hot due to an overload on the circuit, the strip bends, which in turn activates the magnetic element. The magnetic element pulls on a trip lever, which in turn disconnects the circuit, thus protecting it from any further damage. The magnetic element is adjustable, which allows the user to customize the tripping point of the circuit breaker, i.e. the point at which it will trip and disconnect the circuit. This adjustment is called the pickup point or the thermal trip point.

Conclusion

104-PR-3.5A circuit breaker is a type of protective device, which is used to protect electrical circuits from overload or short circuit damage. It works by automatically switching off the circuit when it senses an overload condition or a fault current. It is used in both residential and industrial applications, and its working principle is based on a thermal-magnetic tripping mechanism. The adjustable magnetic element allows the user to customize the tripping point of the circuit breaker.
