Features:
• 200kA interrupting rating complies with NEC®Section 110.9
for today's large capacity systems.
• Fast short-circuit protection and dual-element, time-delay
performance provide ultimate protection.
• Reduces existing fuse inventory by up to 33% when
upgrading to Low-Peak fuses.
• Consistent 2:1 ampacity ratios for all Low-Peak fuses make
selective coordination easy.
• 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.
• Current-limitation protects downstream components against
damaging thermal and magnetic effects of short-circuit
currents.
• A superior, all-purpose, space-saving branch circuit fuse
that meets most protection requirements up to 30A.
• Very compact, with a physical size only 13⁄32" x 11⁄2"
(10.3 x 38.1mm) with rejction tip.
• Proper sizing can provide "no damage" Type 2 coordinated
protection for NEMA and IEC motor controllers.
• 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.
