Product FAQs
7 answersWhich panelboards and enclosures are compatible with the XT5LU330ABYN000XXX?
This breaker is designed for installation in ABB ReliaGear neXT panelboards, ReliaGear SB switchboards, and ABB SACE Tmax XT enclosures.
What does the L in the XT5L frame designation indicate?
The L indicates the interrupting capacity class. For the XT5 frame, the L class provides an extra-high interrupting rating of 100kA at 480VAC and 200kA at 240VAC.
How does the thermal-magnetic trip unit function on this 300A breaker?
It features an adjustable thermal and adjustable magnetic (TMA) trip unit. This allows you to fine-tune both the Long-Time (overload) and Instantaneous (short-circuit) protection settings to match your specific load requirements.
What wire sizes are accepted by the lugs on this breaker?
The included lugs accept two conductors per phase, ranging from 2/0 AWG to 500 kcmil.
Can the ABB Tmax XT5 series replace older GE Spectra circuit breakers?
Yes. Following ABB's acquisition of GE Industrial Solutions, the Tmax XT5 series is the direct modern replacement for legacy GE Spectra SG600 frame breakers. Retrofit kits are available to install XT5 breakers into existing Spectra panelboards.
Is this breaker suitable for single-phase applications?
Yes, XT5 three-pole circuit breakers equipped with thermal-magnetic trip units can be used in single-phase applications up to 600VAC, per UL standards.
Is the XT5LU330ABYN000XXX a current limiting circuit breaker?
Yes, XT5L breakers have undergone tests per the UL489 Standard and are classified as UL current limiting circuit breakers.
