🔍 Key Concepts

• Relationship between the handle position on a molded‑case circuit breaker and its ON/OFF/TRIPPED indications • How the internal contact symbols (1, 2, 3) show whether the circuit is complete or open • Typical location of the TRIPPED position relative to ON and OFF on three‑position breakers

💭 Think About

• Compare the handle angle and position in figure A with figures B and C. Which one appears centered between the other two? • Look at the matching schematic symbol (1, 2, or 3) that would go with figure A: in that symbol, are the contacts open, closed, or in an intermediate position? • On most three‑position breakers, where is the handle when the breaker has tripped due to a fault rather than being manually switched?

✅ Before You Answer

• Make sure you can clearly distinguish which handle position is fully up, fully down, and in between • Verify whether the corresponding schematic for that position shows a continuous path (closed contacts) or breaks (open contacts) • Confirm that you are not confusing the TRIPPED (center) position with the normal ON or OFF positions before choosing your answer
