GE’s Spectra RMS™ molded case circuit breaker line pioneered the use of interchangeable rating plugs and universal internal accessories. Spectra RMS is now Obsolete.
GE Spectra were available in 4 main sizes, with current ratings from 7 to 1200 amperes, and short circuit interrupting ratings up to 100kA @ 480V.
With the superior performance characteristics needed to meet most demanding applications, rounded out by a complete line of OEM accessories, the Spectra RMS line of circuit breakers, motor circuit protectors and molded case switches was the preferred product for most commercial, industrial and OEM applications.
