Circuit Breakers

Circuit breakers are essential components in electrical systems, as they protect the systems from any overloads or short circuits. They are designed to shut off the flow of electricity in the event of a fault in the system. The 219-3-1REC5-38284-11 is an example of a circuit breaker and in this article, we discuss its application field and working principle.

Application field

The 219-3-1REC5-38284-11 circuit breaker can be used for a variety of applications including household and commercial buildings, power distribution centers, industrial control, electrical systems in ships, and more. It is designed to be used for low voltage applications typically ranging from 12-240V and currents between 16-25A.

The 219-3-1REC5-38284-11 offers various features and benefits that make it an attractive choice. It is highly reliable and shock resistant, has high insulation level, can handle high inrush currents, and has a low total impedance. In addition, it is UL recognized and CSA certified, making it a safe and certified choice.

Working principle

The 219-3-1REC5-38284-11 circuit breaker operates on the principle of thermal-magnetic tripping. Thermal-magnetic tripping is when the circuit breaker operates on both a thermal and magnetic principle, where the thermal element is responsible for detecting overcurrents, while the magnetic element detects short circuits. When either of these elements detect an overload or short circuit, they cause the circuit breaker to trip and shut off the flow of electricity.

When a current overload is sensed, the thermal element will heat up from the extra current. If the thermal element continues to heat up, it will eventually reach a predetermined temperature and cause a bimetallic strip to bend, thus opening the switch and interrupting the flow of electricity. In the case of a short circuit, the magnetic element will sense the sudden increase in current and cause an electromagnet to be energized, which in turn pulls a trip lever and opens the circuit breaker.

In summary, the 219-3-1REC5-38284-11 is a reliable and certified circuit breaker that is suitable for a variety of applications. It works on the thermal-magnetic tripping principle and is designed to detect both overloads and short circuits, thus ensuring the safety of the electrical system it is installed in.
