Features:
• A superior all-purpose, space-saving branch circuit fuse that
meets most protection requirements up to 30A
• Very compact; physical size is only 13⁄32” x 11⁄2”
(10.3 x 38.1mm) with” rejection tip
• The unique yellow color makes it easy to tell that the correct
fuse type is installed
• Faster response to damaging short-circuit currents and
higher interrupting rating than mechanical overcurrent
protective devices
• 200kA interrupting rating for available fault current in today's
large capacity systems and helps ensure that future growth
will not obsolete the protection system
• Time-delay characteristic avoids unwanted fuse openings
from surge currents while fast response speed under short-
circuit conditions provides a high degree of current
limitation
• The LP-CC fuse can be sized close to full load ratings for
maximum overload and short-circuit protection
• Can be used where either a time-delay or a fast-acting fuse
is needed, making selection easier and reducing spare fuse
inventories for substantial cost reduction
• Superior protection for small horsepower motor circuits
• Proper sizing can provide “no damage” Type “2”
coordinated protection for NEMA and IEC motor controllers
• Motors receive maximum protection against burnout from
overloads and single-phasing
