Motor control centers have units or buckets with an extendable/retractable power connection (stab) assembly and one or more operating lever interlocks that include a unit latch to latch to a cabinet and a power connection position interlock that blocks the handle of the units or buckets based on position of the power connection assembly, optionally also including a shutter cam that slides a shutter right and left.

Motor control center (MCC) units with retractable power connector and interlocks including a power connector position interlock

Motor control centers have units or buckets with an operator mechanism with a retractable power stab assembly and one or more sliding shutters that controllably block access to a stab isolation port based on position of the operator disconnect handle using an attached shutter cam that slides the shutter right and left.

Motor control center (MCC) units with slidable shutters

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.

Motor control center units with retractable stabs and interlocks

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 buckets with multi-purpose shutter cams that slide shutters right and left to controllably block access to a portal of an isolation lead screw that can extend and retract power connectors and that provides one or more safety interlock engagement features that prevent certain actions depending on the operating state of the buckets.

Motor control center units with multi-purpose shutter cams and related units

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.
