OP1260 Protection Box

The OP1260 is a protection box designed to provide protection, control and isolation of AC and DC lines. In the event of an emergency, the emergency stop button cuts the main MMC power circuit.  Rotary switches on the OP1260 allow operators to isolate incoming high voltage to the MMC circuit (the auxiliary power bar should also be disconnected to completely remove any voltage from the equipment).
