Shop by family (quick start)
If you already know your system, use the Series filter above to narrow fast. These are the families we see most often for replacements and “keep it running” calls:
- I-Line (I / II)
- Pow-R-Way & Pow-R-Way III
- Sentron (standard & low-amp)
- Spectra (SB & low-amp)
- Armor-Clad & FVK
- XJ-L family (XLU / XLX / XLVB)
- CP2 / CP4
- Round Bar (SD type)
- ZTAP
Not sure what you have? That’s normal—Skip the guesswork and send photos (details below). We’ll confirm before you buy.
What you can source here (fast)
- Breaker and fusible styles
- 3- and 4-wire, with and without ground
- Common industrial voltages (including 240, 480, 600)
- Broad range coverage (often 10–5000A and 90–600V, depending on family)
- Replacement fuses and circuit breakers to complete the job
How EMSCO helps you win the day
- Legacy and obsolete systems are our niche: We regularly support Square D, GE, Cutler-Hammer/Westinghouse, Siemens/ITE, Eaton, and other older lines that are hard to source.
- Refurb you can trust: Reconditioned units are inspected and tested and backed by a 1-year warranty.
- Fast match help (with a human): When details matter—stabs, wire/ground, breaker frame, voltage—we help you confirm the exact fit.
Speed up the match (photos work)
If you want the fastest “yes, that’s the one,” send what you have. Even incomplete info is fine.
- Part number(s) and series name (if visible)
- Amperage and voltage
- Wire/ground configuration
- Photos of the nameplate/labels and the stabs/connection points (plus a side/profile shot)
Pro tip: Two clear photos beat a long email. If you can send a nameplate and a close-up of the stabs/connection, we can usually narrow it down quickly.
Refurbished standards (what “R&G” means here)
- Inspected for condition and configuration
- Cleaned and checked for safe, reliable operation
- Tested and backed by a 1-year warranty
Avoid the wrong order
- Series matters: similar-looking plugs can be different families.
- Wire/ground matters: 3-wire vs 4-wire (and ground) changes the fit.
- Style matters: breaker vs fusible, plus breaker frame specifics.
Completing the job (not just the plug)
If you’re expanding a line or finishing a run, we can help you source the related pieces that keep the project moving. See Bus Duct and Tap Boxes & Accessories.
