What is the difference between a QDA32100 circuit breaker and a QDL32100 circuit breaker?

Issue:
What is the difference between a QDA and a QDL breaker?

Product Line:
Circuit Breakers

Environment:
Electrical Distribution Equipment

Cause:
Need to discern between the two similar breakers

Resolution:
QDA style circuit breakers are designed for mounting into an I-Line panelboard, and they have plug-on connectors on the ``on`` side of the breaker and mechanical lugs on the ``off`` side. QDL style circuit breakers have mechanical lugs on both the ``on`` and ``off`` side, and they are designed for application as enclosed circuit breakers, or separately mounted applications.
In this picture, the breaker in back is an I-line breaker type QBA (3-pole), and the two breakers in front are type QBL (2-pole and 3-pole). For dimensions, see the three attached drawings.
