General
The UL recognized component mark on the MCB means that the
component alone meets the requirements for a limited, specific use. These
MCBs are not intended for separate installation in the field, they are
intended for use as a component of complete equipment submitted for
investigation to UL.
The UL Listed mark on the MCB is the manufacturer’s representation that
samples of the complete product have been tested by UL to be used for
most common industrial applications. This superior UL mark allows for field
installation without the need for UL investigation.
