Which type of circuit breaker accessory is designed specifically for drawout circuit breakers?

The accessory specifically designed for drawout circuit breakers is the position switch. This switch is integral to the operation of drawout circuit breakers because it provides critical information about the position of the circuit breaker—whether it is in the connected or disconnected position.

In the context of drawout breakers, the position switch is essential for safety and operational integrity. It ensures that the breaker cannot be energized unless it is properly seated in the disconnect position, helping prevent unauthorized operation and maintaining system safety. This also allows for automatic control systems to monitor and respond to the breaker’s position, enhancing the overall reliability of the electrical distribution system.

Other accessories such as electric lockouts, shunt trips, and operation counters serve different purposes, such as locking out the operation of the breaker for maintenance, remotely tripping the breaker under specific conditions, or tracking the number of operations respectively, but they are not specifically designed for or directly tied to the drawout mechanism functionality.
