ABB / General Electric SELA24AT0030 Molded Case Circuit Breaker

ABB acquired GE Industrial Solutions in 2018. Depending on the manufacturing date, this Spectra RMS circuit breaker may be branded as either ABB or General Electric. Both versions are identical in form, fit, and function.

Yes, GE Spectra RMS SE-frame breakers utilize field-installable, front-mounted rating plugs to establish their continuous ampere rating. To operate at 30 amps, it requires a 30A rating plug, such as the SRPE30A30.

LSI indicates that the solid-state electronic trip unit features adjustable Long-Time, Short-Time, and Instantaneous settings. This allows for precise coordination and true RMS sensing for both sinusoidal and non-sinusoidal currents.

The standard lug kit for this SE-frame breaker is the TCAL18, which accepts 12 AWG to 3/0 AWG aluminum or copper conductors.

When using the standard TCAL18 lugs, torque requirements depend on the wire size. Torque 3/0 to 2 AWG wire to 150 in-lb, 3 to 8 AWG wire to 100 in-lb, and 10 to 12 AWG wire to 35 in-lb.

Yes, the SELA24AT0030 accepts a variety of internal accessories, such as shunt trips, undervoltage releases, auxiliary switches, and bell alarms. These are UL listed for field installation and can be installed without removing the main breaker cover.

Yes, the Spectra RMS SE-frame design allows for reverse feeding. The front-mounted rating plug and internal accessories remain accessible regardless of the feed direction.
