An accessory used to provide remote indication of the breaker main contact position is called a/an _________.

The accessory used to provide remote indication of the breaker main contact position is known as an auxiliary switch. This component is typically attached to circuit breakers and is designed to monitor the open or closed position of the breaker contacts. When the circuit breaker operates, the auxiliary switch changes its state, which can be used to provide feedback or indication to a remote monitoring system or control panel.

This function is crucial in electrical systems where real-time status is necessary for safety and operational efficiency, allowing operators to ascertain whether a breaker is closed (energized) or opened (de-energized) from a distance. The auxiliary switch supports proper system management by integrating into alarms, interlocks, or monitoring systems.

Other accessories mentioned serve different functions: an overcurrent trip switch is involved in interrupting the circuit during overcurrent conditions, a bell alarm is typically used for audibly alerting someone to an issue, and a shunt trip is used to remotely open the circuit breaker under specific conditions. None of these fulfill the same purpose of indicating the breaker contact position as the auxiliary switch does.
