Product FAQs
7 answersWhat panelboards and switchboards is the SKHH3608L3XX compatible with?
This SK frame breaker is designed for installation in GE Spectra Series panelboards and Spectra Series switchboards.
Does this circuit breaker require a rating plug to function?
Yes, GE Spectra RMS SK frame breakers utilize interchangeable rating plugs to set the continuous current limit. A compatible rating plug, such as the SRPK800B800, must be installed in the electronic trip unit for the breaker to operate properly.
What type of mounting and terminal connections does this unit use?
The SKHH3608L3XX features a bolt-on mounting configuration and comes equipped with standard lugs for wire terminations. Verify specific wire range and torque requirements based on the installed lug kit before wiring.
Is the SKHH3608L3XX manufactured by General Electric or ABB?
Originally developed by General Electric as part of the Spectra RMS line, this breaker is now manufactured by ABB following their acquisition of GE Industrial Solutions. Both ABB and GE branded versions share the exact same physical frame and performance specifications.
Is the SKHH3608L3XX frame rated for 100 percent continuous duty?
Yes. The second H in the SKHH catalog prefix indicates that this is a 100 percent continuously rated circuit breaker, meaning it can safely carry its full 800-amp load continuously when installed in an appropriately sized and ventilated enclosure.
What do the LSI trip functions on this breaker stand for?
The LSI designation indicates that the solid state electronic trip unit features adjustable Long-Time, Short-Time, and Instantaneous protection settings. This allows for highly precise overcurrent and short-circuit coordination within complex electrical distribution systems.
Does this electronic trip unit include ground fault protection?
No, the SKHH3608L3XX features an LSI trip unit consisting of Long-Time, Short-Time, and Instantaneous protection. If your system requires equipment ground fault protection, a breaker with an LSIG trip function is required.
