Circuit breakers are an essential part of any wiring system. They provide a crucial layer of safety and protection from potential electric shock, overloads, and other potential risks associated with wiring systems. The 219-2-30497-3 circuit breaker is one of the more advanced models available, incorporating a variety of features and technologies to ensure optimal performance. In this article, we will discuss the application field and working principle of the 219-2-30497-3 circuit breaker.

Application Field

The 219-2-30497-3 circuit breaker is primarily designed for use in residential settings. It is rated for a 15A maximum load and is intended for use in indoor environments. It can be used to protect circuits from overloads and short circuits, and it can also serve as a means of disconnecting a circuit when needed. Additionally, the 219-2-30497-3 circuit breaker is UL Listed, which means it has been tested to meet all applicable safety standards.

Working Principle

At the heart of the 219-2-30497-3 circuit breaker is a thermal-magnetic tripping mechanism. This mechanism is designed to sense both temperature and current levels, and it can respond to either or both of these conditions to trip the circuit breaker and disconnect the current. The thermal-magnetic tripping mechanism consists of a bimetallic strip, a single coil, and a set of contacts that are physically linked to the coil. The bimetallic strip is designed to sense temperature, and when it reaches a certain point, it causes the coil to become magnetized. This magnetization is the key to activating the contacts, which disconnect the current.

The thermal-magnetic tripping mechanism is designed to be triggered when either of the two conditions is met. When the temperature reaches a high level, the bimetallic strip will expand and activate the coil. When current reaches a high level, without it necessarily triggering an overload, the coil will be magnetized and the contacts will be closed. Both of these conditions will cause the circuit breaker to trip, thus disconnecting the current and preventing an overload or fire.

The 219-2-30497-3 circuit breaker also features a quick make-make toggle switch which allows you to quickly switch between the three primary breakers – on, off, and trip. This enables you to quickly respond to an overload or short circuit condition by simply toggling the switch.

Conclusion

The 219-2-30497-3 circuit breaker is a great option for any residential wiring system. Its advanced thermal-magnetic tripping mechanism enables it to respond to both temperature and current levels, providing superior protection against potential overloads and short circuits. Additionally, the quick make-make toggle switch allows it to quickly respond to any changes in the wiring system, making it a great choice for protecting your home or business.
