Circuit breakers are a safety device designed to prevent electrical circuits from becoming overloaded with too much electricity. They are used in commercial and industrial buildings to protect wiring, electrical equipment, and people from potential electrical hazards. Circuit breakers are an important part of any electrical system and are essential for safe operation.

The numbered designation of 219-2-1-66-8-6-100, is a circuit breaker rating that describes both the application field and the working principle. This rating is used to correctly size a circuit breaker for a specific application. It is important to understand the various ratings and their corresponding features before selecting a circuit breaker.

The first two numbers represent the voltage rating. The first number is the highest rated voltage and the second number is the lowest rated voltage. The voltage rating refers to the maximum voltage that can be handled by the circuit breaker. The higher the rating, the better the performance of the circuit breaker.

The next two numbers represent the current rating, usually expressed in amps. The first number is the highest rated current and the second number indicates the lowest rated current. The current rating describes how much current the circuit breaker can safely handle. The higher the rating, the greater the capacity of the circuit breaker to protect electrical systems.

The next two numbers represent the fault breaking capacity of the circuit breaker. The first number is the highest fault breaking capacity and the second number indicates the lowest fault breaking capacity. The higher the rating, the better the ability of the circuit breaker to shut off the circuit in the event of an overload.

The final two numbers refer to the short-circuit capacity. The first number is the highest rated short-circuit capacity and the second number indicates the lowest rated short-circuit capacity. The higher the rating, the better the ability of the circuit breaker to shut off the circuit in the event of a short circuit.

In conclusion, the 219-2-1-66-8-6-100 is a circuit breaker rating that describes both the application field and working principle. Understanding this rating is essential for selecting the correct circuit breaker for a given application and ensuring the safety of people and electrical equipment.
