Description:
Features and benefits
•ꢀ
Industry’s only UL Listed and CSA Certified fuse
Ultimate protection Class RK1 dual element,
current-limiting, time-delay fuses available with
optional open fuse indication. Time-delay – 10
seconds (minimum) at 500% of rated current (8
seconds for 0-30A sizes).
with a 300 kA interrupting rating that allows for
simple, worry-free installation in virtually any
application.
•ꢀ
Fast short-circuit protection and dual-element,
time-delay performance provide ultimate
protection.
Specifications:
•ꢀ
Reduces existing fuse inventory by up to 33%
Ratings
when upgrading to Low-Peak fuses.
•ꢀ
Volts
•ꢀ
Consistent 2:1 ampacity ratios for all Low-Peak
fuses make selective coordination easy.
•ꢀ 250 Vac
•ꢀ 125 Vdc
•ꢀ
Time-delay permits 130% FLA sizing for back-up
motor protection.
•ꢀ
Amps 1/10-60A
•ꢀ
•ꢀ
Current-limitation protects downstream
IR
components against damaging thermal and
magnetic effects of short-circuit currents.
•ꢀ 300 kA Vac RMS Sym.
•ꢀ 100kA Vdc
•ꢀ
Protects against single-phase motor damage.
Agency Information
