Circuit breakers are passive devices used in electrical switching systems. They protect electrical circuits from damage caused by over-current or short-circuit conditions. Circuit breakers are also used to protect electronic devices from damage caused by electrical surges, and to restore power in the event of a power failure. The 219-3-21758-1 circuit breaker is a two-pole, air-magnetic circuit breaker. It is capable of operating at up to 115 volts, and providing protection for both AC and DC applications.

The main components of the 219-3-21758-1 circuit breaker are two contact points, one set of main contacts, and one set of auxiliary contacts. The main contact points contain a set of bimetallic strips that are heated by the current passing through the circuit. When the current exceeds the rated levels for the circuit breaker, the bimetallic strips become heated and expand, causing the contact points to close, thus cutting off the circuit. The auxiliary contacts are used to provide an additional safety feature and can be connected to a pilot light or a warning bell if desired.

The 219-3-21758-1 circuit breaker can be used for both AC and DC applications. In AC applications, the circuit breaker will open when the current exceeds the rated value for the breaker. In DC applications, the breaker will open when the voltage exceeds the rated value. The circuit breaker can also be used to protect devices or circuits from damage caused by electrical surges.

The 219-3-21758-1 circuit breaker is designed to be rugged and reliable in harsh environments. It is designed to operate efficiently within a temperature range of -25°C to +60°C, making it suitable for use in a variety of applications. The circuit breaker also has a high dielectric strength, allowing for greater protection in industrial and laboratory applications. Additionally, the circuit breaker features an inherent time delay feature which allows it to react quickly when the current exceeds its rated value, thus providing protection for long-term applications.

The 219-3-21758-1 circuit breaker is ideal for a variety of applications, including industrial and laboratory equipment, as well as residential and commercial electrical systems. It provides reliable and efficient protection from over-current and short-circuit conditions, as well as protection from electrical surges. This is an ideal device for use in a variety of applications, both for DC and AC purposes. In addition, it provides a high level of protection at a very affordable price.
