Product FAQs
7 answersWhat does the "P" in the SKPB36BD1200 catalog number signify?
The "P" indicates the interrupting capacity tier within the GE Spectra RMS SK frame family. The SKP frame designates a high interrupting rating of 100kA at 480VAC.
What do the LSIGT functions on this trip unit stand for?
LSIGT stands for Long-Time, Short-Time, Instantaneous, Ground-Fault, and Targets. This solid-state electronic trip unit allows precise adjustments for each of these protection parameters, with visual targets to indicate the cause of a trip.
Can I change the amperage rating of this 1200A breaker?
Yes, GE Spectra RMS breakers use interchangeable rating plugs. You can install a compatible SRPK1200A series rating plug into the front of the breaker to establish or lower its specific trip rating without replacing the entire frame.
What lug kits are compatible with the SK1200 frame?
This breaker accepts various lug kits depending on your conductor size and material. Common compatible lug kits for the SK1200 frame include the TCAL124 and the TCALK2125 for terminating copper or aluminum cables.
What is the modern ABB replacement for the legacy GE SKPB36BD1200?
ABB has replaced the legacy GE Spectra RMS SK1200 frame with the Tmax XT7 series. Upgrading to an XT7 breaker in an existing GE Spectra panelboard or switchboard requires a specific retrofit kit for proper installation.
Does this breaker provide true RMS sensing?
Yes, the solid-state electronic trip unit utilizes true RMS current sensing technology. This provides accurate monitoring and responds to overcurrent conditions without nuisance tripping, even for non-sinusoidal loads like variable frequency drives or computer power supplies.
Can the SKPB36BD1200 be reverse fed?
Yes, GE Spectra RMS circuit breakers, including the SK1200 frame, are designed to allow reverse feeding. The front-mounted rating plugs and internal accessories make this possible without compromising protection.
