Issue:
Selection of I-Line circuit breaker busway plugs and the type of breaker included in each device.

Product Line:
PTLVB - Busways Power IEC & NEMA

Environment:
I-Line Busways are sold and supported in the USA.

Resolution:
The Legacy circuit breakers for I-Line busway plugs are now obsolete and have been replaced by the Powerpact circuit breakers. Selection based on SCCR and trip unit required.
Refer to the online Digest for a selection of current devices.

These busway circuit breaker plug-in units all use P frame breakers. The PTPA unit uses a PA breaker (80% rated). The PTPH unit uses the high short circuit version of the PA breaker. The breaker is a PH ( 80% rated). The PTPE uses a 100% rated micrologic breaker (PE).
