General Electric SKHA26AT0800 Circuit Breaker

Yes, this Spectra RMS circuit breaker requires a front-mounted, field-installable rating plug (such as the SRPK800A series) to establish its continuous ampere rating. The breaker will not function properly without the correct rating plug installed.

The standard lug terminal kit for this SK-frame breaker is the GE TCAL81. This lug kit accommodates three conductors sized from 3/0 AWG to 500 kcmil (Al/Cu) per phase. Lugs are typically sold separately.

LSI stands for Long-Time, Short-Time, and Instantaneous trip functions. On the SKHA26AT0800, the Long-Time pickup is determined by the installed rating plug, while the Short-Time and Instantaneous settings are adjustable to allow for precise coordination with other protective devices in your system.

The SKHA26AT0800 is built on an 800A maximum frame size. The actual continuous current rating is determined by the specific rating plug installed, which can range from 300A up to the full 800A capacity of the frame.

Yes, this solid-state molded case circuit breaker is suitable for reverse feed applications, allowing power to be supplied to either the top or bottom terminals without compromising the breaker's protective functions.

The digital trip system uses true RMS sensing to accurately measure both sinusoidal and non-sinusoidal currents. This ensures reliable protection and prevents nuisance tripping in environments with high harmonic distortion, such as facilities with variable frequency drives or heavy IT equipment.

ABB acquired GE Industrial Solutions in 2018. As a result, Spectra RMS circuit breakers manufactured after the transition may feature ABB branding, GE branding, or a combination of both. The form, fit, and function remain identical regardless of the label.
