Should I repair, recondition, upgrade, or replace my Eaton SPB breaker?

It depends on condition and goal. If the breaker is aging but serviceable, reconditioning / apparatus life extension keeps your SPB switchgear in service. If an SPB-50 or SPB-65 is now under-rated for the site’s available fault current, the drop-in SPB-100 upgrade adds 100 kA with no structural changes. If a breaker has failed, Voyten replaces it from stock — new or reconditioned with a 1-year warranty. Voyten Electric, the New Surplus authorized SPB source and a PEARL founding member, performs all of these. Call 1-800-458-4001.

My Eaton SPB breaker failed in a critical facility — what now?

Call Voyten Electric 24/7 at 1-800-458-4001. As the New Surplus authorized SPB source, Voyten can pull an exact-match new or reconditioned SPB breaker, Digitrip RMS trip unit, rating plug, or part from stock, test it, and ship next-day air — and can provide a rental or swap-out to restore power while a permanent fix is arranged.

Can I upgrade an under-rated SPB-50 or SPB-65 without replacing the switchgear?

Yes. The SPB-50, SPB-65, and SPB-100 share identical external dimensions, so an SPB-100 drops directly into an existing SPB-50 or SPB-65 cubicle with no structural, bus, or control-wiring changes — a clean 100 kA upgrade when the available fault current at a site has grown past the original rating. Voyten supplies the drop-in SPB-100 and all renewal parts.

Can Voyten keep my plant running while I decide?

Yes — Voyten offers rental services and swap-out programs so a tested SPB breaker keeps the plant energized while reconditioning, an upgrade, or sourcing is completed.

Why Extend the Life of SPB Switchgear

In current manufacturing industries, you cannot simply accept that an electrical product is out of production and decide you need to change it all. Full switchgear replacement is among the costliest and most disruptive options — and rarely necessary for SPB, which has been manufactured continuously since 1976 and remains fully supportable.

Voyten Electric adds today's technology to yesterday's electrical equipment, giving you the most for your investment. Aging SPB gear can be reconditioned, fitted with modern Digitrip RMS trip units, and — where fault current has outgrown the rating — upgraded to 100 kA with a drop-in SPB-100. Remanufactured equipment is always worth the investment.

As the New Surplus authorized aftermarket source for the Eaton/Cutler-Hammer/Westinghouse SPB line, Voyten keeps complete breakers, Digitrip RMS units, rating plugs, and renewal parts available — so the recondition, upgrade, and replace options stay open for decades-old installations.
