Trip setting:

The trip setting is the current at which the breaker will trip. The trip setting is typically set to a value that is slightly higher than the maximum current that the circuit is expected to draw. *

Delay setting:

The delay setting is the amount of time that the breaker will wait before tripping after the current exceeds the trip setting. The delay setting is used to prevent the breaker from tripping due to momentary surges in current. *

Reset button:

The reset button is used to reset the breaker after it has tripped. The reset button should only be used after the problem that caused the breaker to trip has been corrected. *

Test button:

The test button is used to test the breaker to make sure that it is working properly. The test button will cause the breaker to trip, even if the current is below the trip setting. ### How to Set Abb Circuit Breaker Settings Setting the correct settings on an Abb circuit breaker is important for ensuring that the breaker will function properly.
