How Does a Mini-Breaker Operate?

In the normal condition, current flows though the arm terminal, down through the very low resistance contact point, and out through the base terminal. The mini-breaker can be triggered from either an increase in the environmental temperature or from excessive current flows. Once the trip temperature has been reached, the bi-metal disc heats and flexes, causing the arm to open.
