Local trip on the front
The SafeGear MCC can be provided with latched or unlatched controllers
The type latch controller has the feature of mechanical interlock, where its contacts remain closed in spite of loss energy.
A button in front of the controller (Fig.1) is used for manual trip manually when deenergized.
The trip mechanism is located on the contoller compartment door (Fig. 2). This is an optional feature that can be requested when the MCC is ordered.
