🔍 Key Concepts

• Molded-case circuit breaker (MCCB) normal handle positions (ON, OFF, TRIP) • How a circuit breaker indicates a fault or overload versus a normal open/closed condition • Difference between tripped and reset states on protective devices

💭 Think About

• Think about what happens to the breaker handle when a fault occurs and the breaker opens automatically. Does it go fully to ON or OFF, or somewhere in between? • Which handle position would a technician look for to know the breaker opened because of a fault, not because someone manually turned it off? • Consider what you normally have to do to a breaker after it has responded to a fault before you can turn it back ON.

✅ Before You Answer

• Identify which option describes the automatic protective action of the breaker (not a manual action). • Recall that resetting and tripping are two different stages—one is the result of a fault, the other is what you do afterward. • Verify which condition is usually shown by the handle being in a mid-position rather than fully at one end.
