Product FAQs
7 answersWhat panelboards are compatible with the SELA24AT0150 circuit breaker?
This breaker is designed for use in GE Spectra Series panelboards, switchboards, and motor control centers. Specific mounting hardware kits, such as the AMCB6EBFP for bolt-on APN panels, may be required depending on your enclosure.
How does the LSI electronic trip unit function on this breaker?
The solid-state electronic trip unit provides adjustable Long-Time, Short-Time, and Instantaneous (LSI) protection. This allows for precise coordination with other protective devices in the electrical system, offering more flexibility than standard thermal-magnetic breakers.
What wire sizes are accepted by the standard lugs on the SELA24AT0150?
The standard lugs accept wire gauges from 12 AWG up to 3/0 AWG. They are rated for use with both aluminum and copper conductors.
Is there a difference between the ABB and GE versions of the SELA24AT0150?
No, they are the exact same product. Following ABB's acquisition of GE Industrial Solutions, Spectra RMS circuit breakers may feature either ABB or GE branding, but the form, fit, and function remain identical.
Does the SELA24AT0150 require a rating plug?
Yes, this Spectra RMS SE150-frame breaker requires a field-installable, front-mounted rating plug to establish the continuous ampere rating.
What advantages does the digital RMS sensing trip system offer?
The digital RMS sensing technology accurately measures both sinusoidal and non-sinusoidal currents. This ensures reliable protection and prevents nuisance tripping in environments with high harmonic distortion, such as those with variable frequency drives or heavy electronic loads.
Is the SELA24AT0150 suitable for reverse feed applications?
Yes, Spectra RMS circuit breakers in the SE150 frame are suitable for reverse feed, enhancing installation flexibility in various panelboard and switchboard configurations.
