  • Motor control center units with retractable stabs and interlocks using sliding portal shutters
    Patent number: 10020642
    Abstract: 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.

  • BUCKET ASSEMBLIES WITH ELECTRICALLY GROUNDED FRONT PANELS FOR MOTOR CONTROL CENTERS AND RELATED MOTOR CONTROL CENTERS
    Publication number: 20180139856
    Abstract: 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.

  • Compact dual feeders for circuit breakers and related buckets and motor control centers (MCCs)
    Patent number: 9871355
    Abstract: 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.
