  • a)
    O–t–CO–T–CO
  • b)
    O–CO–t–CO–T–C
  • c)
    O–C–t–OC–T
  • d)

-C (t=3 sec); T-3min, repeated continuously
b)C-O (t=3 sec); T-3min, repeated continuously
c)O-C (t=3 sec); T-3min, repeated continuously
d)C-O (T=3min); repeated continuously

Answer: c) O-C (t=3 sec); T-3min, repeated continuously. This sequence represents the rated operating duty cycle of a circuit breaker, where the breaker is opened and closed (O-C) with a time delay of 3 seconds (t=3 sec) and the cycle is repeated continuously with a time interval of 3 minutes (T=3min). This duty cycle ensures that the circuit breaker operates reliably and safely under normal operating conditions.
