Circuit Breakers

The IUGH12-1REC4-40681-1 is an example of a circuit breaker, an electrical device designed to prevent circuits from being overloaded. A circuit breaker works by automatically interrupting a circuit when an overload, short-circuit, or ground fault is detected. This can prevent damage to wiring and equipment, and also helps prevent electrocution.

Applications

Circuit breakers are used in many different applications. In residential settings, they are used to protect individual circuits and to protect the entire electrical system from overload. In commercial and industrial settings, they are used to protect machinery, lighting systems, and other electrical equipment. They are also used to prevent potential shock and fire hazards caused by improper wiring or equipment failure.

Working Principle

The IUGH12-1REC4-40681-1 circuit breaker uses a thermal-magnetic switch to recognize and protect against overloads and short circuits. The thermal element senses the current in the circuit and increases the temperature of the bimetal disc when the current reaches a certain level. The increased temperature causes the disc to bend and open the contacts of the breaker, interrupting the circuit. The magnetic element senses the current in the circuit and triggers the trip when the current exceeds a certain level. The breaker uses a spring-loaded mechanism to open the contacts, interrupting the circuit.

The IUGH12-1REC4-40681-1 circuit breaker also has manual reset and trip indicator functions to provide information when the breaker trips. Manual reset allows the breaker to be reset after a fault has been cleared, while the trip indicator provides information on the current in the circuit. This enables the breaker to be reset more quickly and safely, without the need for manual reset.
