MCC buckets, combination motor starters, NEMA and IEC contactors, overload relays, reduced voltage starters, and motor control components: current production and discontinued lines. Edmundson Industrial supplies active lines and sources obsolete and hard-to-find MCC buckets that standard distributors no longer carry.
Motor control centers are among the longest-lived electrical infrastructure in industrial plants. An MCC installed in the 1970s or 1980s may still be in service and require replacement buckets, starter units, and components that were long ago discontinued by the original manufacturer. When that happens, standard distribution has nothing to offer.
Edmundson Industrial supplies current production motor control components (Eaton, Square D, Siemens, Allen-Bradley) and sources discontinued and obsolete MCC buckets, combination starters, and legacy motor control equipment through surplus and specialty inventory channels. If the MCC in your plant is original equipment, send us the nameplate data from the unit that needs replacement and we'll check what's available.
Motor control applications cover a range of starting methods, control configurations, and motor sizes. These are the product categories we handle most frequently.
Pre-wired, plug-in motor control units designed for installation into motor control center line-ups. Available for current MCC generations and sourced for discontinued and obsolete MCC families.
Motor contactors for across-the-line starting, reversing, and multi-speed applications. NEMA sizes for North American applications; IEC frame sizes for imported and modern equipment.
Thermal and electronic overload relays for motor protection. Legacy bimetallic heater elements frequently requested as replacements in older starters and MCC buckets.
Reduced voltage starting methods for large motor loads requiring current-limited starts. Autotransformer, part winding, wye-delta, and solid-state soft starter configurations.
Combination motor starters integrate a disconnecting means, overcurrent protection, and a contactor-overload assembly in a single enclosure. Used in panel-mounted and freestanding applications outside of MCC line-ups.
Replacement structural and bus components for existing MCC line-ups, bus bars, bus plugs, vertical bus covers, incoming line sections, tie sections, and hardware for existing MCC installations.
Replacing an entire MCC line-up is expensive and disruptive. When a single bucket fails or needs to be upgraded and the rest of the line-up is serviceable, the most cost-effective path is a replacement bucket that fits the existing structure, not a whole-system replacement.
The challenge is that many MCC product lines have been discontinued by the original manufacturer. A plant running Westinghouse Type W MCC, older Square D Model 1 or Model 4 equipment, or Cutler-Hammer before the Eaton consolidation may find that standard distributors can't supply a replacement bucket that fits the existing structure and bus system.
Edmundson Industrial sources replacement buckets for discontinued MCC lines. We need the MCC manufacturer, model designation, bucket type, motor HP or FLA, and voltage to check availability. Photos of the existing unit are helpful, especially the nameplate data from the bucket being replaced.
The more of this you can provide, the faster and more accurately we can check availability and quote a replacement:
Eaton Freedom Series contactors and starters, A200 NEMA starters, and current MCC product lines. Legacy Cutler-Hammer and Westinghouse motor control equipment available through sourcing channels.
Model 6 MCC, Bulletin 9998 combination starters, NEMA and IEC contactors, TeSys D and K series. Legacy Model 1, Model 4, and Model 5 MCC components through sourcing.
Siemens NEMA and IEC contactors, combination starters, and WC MCC components. Legacy Furnas and ITE motor control equipment available through sourcing channels for older line-up replacements.
Bulletin 509 NEMA starters, Bulletin 100 IEC contactors, 592 overload relays, Bulletin 2100 and 2107 MCC. One of the most widely installed motor control platforms in U.S. industrial facilities.
ABB AF series contactors and motor starters for IEC applications. MO and MS series manual motor starters. Widely used in imported equipment and modern MCC installations requiring IEC components.
Westinghouse Type W and Series 18 MCC buckets, Furnas combination starters and contactors, ITE motor control, sourced through surplus and specialty inventory channels for older plant equipment.
For current-production starters and contactors, the catalog number is the fastest path. For MCC bucket replacements, the MCC line-up manufacturer, model designation, bucket type, HP/FLA, and voltage are the key inputs.
Current lines are checked against active supply. Discontinued MCC buckets and legacy motor control equipment are checked against surplus and specialty inventory. Response includes availability, condition, and pricing.
Every quote specifies whether parts are new, surplus, or reconditioned. For sourced units, we describe condition specifically: not just "used." Lead time reflects actual availability, not a general estimate.
Approved quotes proceed to order. In-stock items ship from Houston, TX. Sourced items ship when received from the supply channel. We communicate on ship dates and provide tracking.
