What is 3WL air circuit breaker?
3WL air circuit breakers are used as incoming-feeder, coupler, and outgoing-feeder circuit breakers in electrical systems in industry, buildings, and infrastructure applications. They have communications capability and can be easily integrated into higher-level control and energy management systems.
What is a circuit breaker service?
Circuit breaker is an established design pattern that applications implement to prevent a failure in one part of the system from cascading to the rest of the system. In an architecture with distributed applications, such as microservices, many services call other services running on remote servers.
How does a Circuitbreaker work?
Instead of transferring that heat to the appliances and electronic items plugged into your outlets, causing them to burn out and potentially resulting in a fire, the circuit breaker trips. This shuts off the electricity to the entire house or to that select zone at its distribution point.
