What ensures that the circuit breaker remains closed during a voltage drop?

The Undervoltage Trip coil is essential for ensuring that a circuit breaker remains closed during a voltage drop. When the voltage in the electrical system falls below a certain threshold, the Undervoltage Trip coil is designed to lose its activating force, which can trigger the circuit breaker to open automatically. This safety feature is crucial in protecting electrical equipment from damage that can occur if a circuit breaker were to remain closed during inadequate voltage conditions.

In contrast, the Electric Lockout device prevents unauthorized operation of the circuit breaker by physically blocking its mechanism, which does not directly relate to maintaining its closure during a voltage drop. The Electrical Closing Push Button is used to manually close a circuit breaker but does not influence its operation during voltage drops. Lastly, the Operations Counter tracks the number of times a circuit breaker has opened or closed but does not have a role in maintaining its state during voltage fluctuations.
