A closing circuit combines an operator or automatic request with the conditions that allow the breaker to close. The closing coil releases stored mechanism energy where that construction is used; it is different from the spring-charging motor.","In a switchgear bus-coupler panel, a close request is checked against position, mechanism readiness and the selected live-bus or dead-bus conditions before the closing circuit is enabled.

Communication success does not prove breaker movement.","Follow request, permission and final coil output as separate signals.
