What safety protocol is followed when the Automatic Coupler Control MCB is tripped?

The application of the emergency brake system is essential in maintaining safety protocols when the Automatic Coupler Control MCB (Miniature Circuit Breaker) is tripped. This protocol ensures that the train or traction unit can quickly come to a stop, preventing any potential accidents or injuries that could arise from unexpected movements. The emergency brake serves as a critical safeguard to control the speed and ensure the safety of passengers and crew.

Implementing this protocol minimizes risks associated with electrical failures or disruptions in the automatic coupler control system, facilitating a rapid response to protect the integrity of the train operation. Other options, while they may be relevant in their context, do not prioritize immediate safety in the way that quickly engaging the emergency brake does.
