Features:
• 200 kA 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 amp rating 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 fault conditions provides
a high degree of current limitation.
• Current-limitation protects downstream
components against damaging thermal and
magnetic effects of fault currents.
• A superior, all-purpose, space-saving branch
circuit fuse that meets most protection
requirements up to 30 A.
• Very compact physical size that’s only 13/32” x
1-1/2” (10 x 38 mm) 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.
