Time-delay – 12 seconds (minimum) at 200% of rated current. Specifications: 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 1 1⁄2” (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.
