Bussmann 15CLE1-50E – Frequently Asked Questions

1) What amp rating and interrupting capacity does the Bussmann 15CLE1-50E fuse have?
The 15CLE1-50E is a 30A E-rated current-limiting fuse with a 63 kA interrupting rating. That interrupting figure is what matters on a medium-voltage feeder or transformer circuit: the available fault current at the point of installation has to be at or below 63 kA for the fuse to clear it safely.
2) Can the Bussmann CLE Series fuse be used in an outdoor enclosure, or is it indoor only?
Both. The CLE Series 15CLE1-50E is listed for indoor and outdoor use, so it works in indoor switchgear and in outdoor pad or pole-mounted distribution equipment alike, provided the holder and enclosure are suited to the location.
3) What does E-rated mean on a medium-voltage fuse like the 15CLE1-50E, and how is it different from an R-rated fuse?
E-rated means the fuse follows the standard melting-time characteristic used for general-purpose medium-voltage circuits, so it is the type specified for transformer primaries, feeders, and potential transformer circuits. R-rated fuses are a different animal: they are back-up protection for medium-voltage motor starters and are selected with a contactor and overload relay, not by amp rating alone. The 15CLE1-50E is the E-rated, 30A type, so it belongs on distribution and transformer protection, not as a motor-starter fuse.
4) Is the Bussmann 15CLE1-50E a single-barrel fuse or a multi-barrel unit?
Single barrel. That keeps it to one body in a standard fuse clip or holder, which is what you want when you are replacing a like-for-like unit in an existing switch or drawout assembly. Multi-barrel versions of medium-voltage current-limiting fuses exist for higher continuous current, but this 30A unit is not one of them.
5) What is the correct Bussmann part number to order for a 30A CLE current-limiting fuse?
Order by manufacturer part number 15CLE1-50E. That is the exact Bussmann catalog designation for the 30A E-rated CLE Series current-limiting fuse, and medium-voltage fuses are not cross-interchangeable by amp rating alone, so the full part number is what should go on the requisition.
6) Why choose a current-limiting fuse instead of a standard expulsion fuse for switchgear protection?
A current-limiting fuse like the CLE Series clears the fault before the first half-cycle peaks, cutting the let-through energy that reaches downstream equipment and the people working near it. Expulsion fuses vent gas and let the full fault current flow until a natural current zero, which is why they are not used inside enclosed indoor switchgear. With a 63 kA interrupting rating, the 15CLE1-50E is aimed at installations where available fault current is high and let-through has to be held down.
7) What kind of equipment is the Bussmann CLE 30A fuse typically installed in?
Medium-voltage distribution gear: transformer and feeder circuit protection, indoor switchgear, outdoor electrical enclosures, panelboards, and power distribution equipment. It goes in the fuse holder or clips of that equipment rather than being mounted on its own.
