Abstract: A hydraulic multi-pole actuation system opens all poles of a circuit interrupter simultaneously. The system utilizes Thomson coil arrangements with a wide piston attached to the conductive member of each arrangement. A narrow piston is attached to the movable conductor of each pole assembly in the circuit interrupter. The wide and narrow pistons are contained within a hydraulic tank. Activating the Thomson coils causes the wide pistons to displace the hydraulic fluid, and the displaced fluid pushes against the narrow pistons to cause the movable conductors to open the line connections in their respective pole assemblies. The wide pistons have a greater collective surface area that interfaces with the hydraulic fluid than the narrow pistons do, enabling fewer Thomson coils arrangements to be used than there are poles in the circuit interrupter, and enabling movement of the wide pistons to be amplified during translation into movement of the narrow pistons.

Abstract: A power unit in a motor control center comprises an extendable/retractable carriage assembly and a power connection configurable to prevent an operator from accidentally energizing the power unit. A carriage follower coupled to the carriage assembly and in contact with a rotatable linkage may rotate the rotatable linkage to position an operator handle blocking surface. In a blocking position, the blocking surface prevents rotation of an operator handle to an operator handle position associated with energizing the power unit and in a nonblocking position, the blocking surface allows rotation of the operator handle to the operator handle position associated with energizing the power unit.

Abstract: Systems and methods are provided for monitoring the effects of conductive dust deposits that compromise the ability of a trip unit to accurately detect AC current in a circuit interrupter. When a Rogowski coil is used as a current sensor in the circuit interrupter and the trip unit processes the output of the Rogowski coil using a printed circuit board assembly (PCBA) processing circuit, the DC component of the processing circuit output signal can be analyzed to determine whether any conductive dust has formed unintended electrical pathways on the PCBA and compromised the ability of the PCBA to accurately measure AC current in the circuit interrupter. It can be determined that such unintended electrical pathways have formed when the DC component of the processing circuit output either exceeds a predetermined threshold or has increased by a significant amount after opening of the separable contacts.
