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%
