Stocked components for equipment builds and maintenance.

No part is interchangeable simply because it looks similar. A reference number, familiar brand or broad product description can help identify a candidate. It does not establish the exact configuration required by a machine or project. Start with the controlling part number, drawing or specification and compare the full item.

The directory is a secondary offer alongside build to print fabrication. It helps a buyer request industrial components through the same parts conversation. It does not claim an advantage on price, an exclusive supply route or approval by a data center owner. The value of a line item depends on its fit, availability and quoted terms.

The directory covers electrical controls, circuit protection, raceway, cable handling and site support items. Use the part family to narrow the search, then compare the exact item with your equipment requirement. A category name cannot resolve the required voltage, connection, size, material or approval for a particular application.

For replacement work, start with the equipment model and the manufacturer part number on the approved parts list. For a new build, use the released bill of materials. If a required detail is missing, include it in the quote request before choosing an item.

The November 2026 catalog includes these SKU and product line counts. They describe the range of items available for quote review, not units ready to ship.

• 150 fuse SKUs: Bussmann FRN-R and FRS-R, Littelfuse FLQ, one-time and glass fuses.
• About 160 contactor, starter, contact kit and auxiliary SKUs: Sprecher and Schuh, Allen-Bradley, Siemens, Square D and Furnas.
• 31 soft starter SKUs, 35A to 168A: Sprecher and Schuh PCEC and Nordic Y-delta. Suitable fixed speed applications only, with no VFD substitution.
• About 135 generic plug-in relay, socket and phase monitor SKUs: Omron, Potter and Brumfield and SSAC.
• About 330 wireway, EMT, flexible conduit and box SKUs.
• 70 Kellems mesh grip sizes, listed as catalog SKUs and product lines.

A separate grooved piping hardware family has 169 catalog SKUs in sizes from 1.5 to 4 in. Gasket grade and manufacturer are confirmed to your spec. These lines sit outside the main 1,720-SKU industrial component directory. Request a separate quote review of the exact configuration; no approval for chilled water service is implied.

The DCM part number identifies the catalog line for your inquiry, such as DCM-PCEC-074-600V-120V. It is a catalog identifier, not a claim that we manufacture the original equipment component. The manufacturer reference remains separate. Confirm the actual maker, full model and configuration when a source reference is incomplete or includes comparison numbers.

The unit of measure is also part of the request. An EA, pack or length can represent a different order quantity even when the description looks familiar. State the quantity you need in the listed unit and explain any pack size requirement. The quote should make the unit, exact part and included items clear.

The motor control range includes soft starters, contactors, starters, contact kits and auxiliary blocks. For a motor control request, include the full manufacturer part number, line voltage, control voltage and duty requirements. Give the equipment model or approved bill of materials if this is a replacement part.

Soft starters belong only in suitable fixed speed motor applications. They are not substitutes for a variable frequency drive. A current rating alone does not establish a match. The buyer must confirm the motor connection, control functions, protection coordination and other requirements for the actual application before accepting the item.

For a fuse, specify the exact class, current, voltage, interruption rating and physical form required by the equipment. A similar size or a higher current rating is not an acceptable basis for a substitution. Preserve the manufacturer part number from the approved list when the specification requires it.

For a relay, include coil voltage, AC or DC, contact arrangement, contact rating, socket and any required indicator or suppression option. Phase monitors and timers need their full operating range and function identified. Catalog names can abbreviate these details, so request the current datasheet and exact supplied configuration where the choice matters.

The directory includes wireway and trough, EMT, flexible conduit, boxes, fittings and cable support items. Match the exact size, material, connection method and required approvals. Include covers and fittings in the request if the delivered scope needs them. A straight section alone may not make a complete route.

Kellems mesh grip selection needs the cable size range and the required grip style. Include the application and any specified manufacturer number. Do not choose a grip by appearance or by a single nominal dimension. The buyer or installer must verify the grip against the manufacturer requirements for the actual cable and use.

A pressure gauge kit needs to match the service and the test procedure. Confirm the range, connections, hose and adaptor ratings, materials and any calibration requirement before use. Include the fluid and required pressure in the request. A kit intended for another service does not establish cooling fluid compatibility or approval for your test.

Battery requests need the exact model, voltage, capacity, terminal type and dimensions. Include the equipment requirement and any date code or warranty conditions. Small control batteries listed in this catalog do not establish a complete data center UPS battery system offer. Confirm the individual configuration and intended service before accepting the quoted item.

The directory also includes PPE, barricades, tools, meters and maintenance supplies. Select these against the actual task and site requirements. A broad safety product name does not establish the protection level needed for electrical work or another specific hazard. The responsible site team must define the required equipment.

If you need a complete kit, list its contents and quantities. Include any required certification, calibration, shelf life or product documentation. These details belong in the quote request just as they do for an electrical component. A catalog listing makes an item easy to identify, but it does not replace the user’s selection process.

Use the request quote button next to a row to carry the DCM part number into your inquiry. Add the quantity, destination and needed date. Include the controlling manufacturer number or specification in the notes, especially when the catalog reference is incomplete. Ask for any required traceability, warranty or supporting documentation.

Stock counts and prices change, so they are not published here. The quote must confirm the offered item and current supply position. Your designated technical authority gives final application approval. Keep technical fit, supply availability and the commercial offer separate until each one has been reviewed.
