Motor control centers have units or buckets with one or more sliding shutters that controllably block access to a stab isolation port based on position of the operator disconnect handle using attached cams that slide the shutter right and left. A front panel of the unit or bucket may also be configured to pivot out about a long axis associated with a bottom long side thereof.

Switch handle for circuit breakers

Circuit breakers with a rotary handle attached to an inwardly oriented shaft that connects to a gear assembly that translates rotational input to linear input also include a trip assist spring in communication with the rack gear so that, in operation, the trip assist spring applies a force to the operator slider and forces the handle to a consistent trip position.

Bucket assemblies for motor control centers (MCC) with disconnect assemblies and related MCC cabinets and methods

Motor control centers have units or bucket assemblies with a spring-loaded front panel attached to a housing of the unit by a laterally extending metallic shaft that allows the front panel to pivot open about a long axis of the shaft. When closed, the bottom of the front panel slidably receives and is in abutting contact with the shaft which provides an electrical ground.

Motor control center units with retractable stabs and interlocks using sliding portal shutters

Motor control centers have units or bucket assemblies with a front panel configured to pivot about a long axis associated with a bottom long side thereof and slide radially with respect to the shaft, away from the shaft in an open position to thereby position the front panel a distance away from the shaft to be able to fully open to at least ninety degrees.

Dual starters and/or feeders are positioned in a unit housing to be offset from one another in a front to back direction to provide a compact configuration for a MCC cabinet. The dual starters or feeders can communicate with a respective external handle attached to an inwardly oriented shaft. The handles can be rotary handles that connect to a respective gear assembly that transforms rotational input to linear input.

Disconnect operating handles for circuit breakers are configured with a rotary handle attached to an inwardly oriented shaft that connects to a gear assembly that translates rotational input to linear input. The disconnect operating handles include pivoting lockout levers that can automatically 'pop' out to expose the lockout space for a padlock when a user touches the lever in an appropriate location.
