• CE
Features:
• Dual-element feature provides the best
time-delay performance, allowing closer
sizing and superior protection of motors and
transformers
• Closer sizing allows for smaller fuses and
less costly switches
• Class RK5 fuses with a 200 kA interrupting
rating for use in a broad range of
applications
• Provides motor overload, ground fault, and
short-circuit protection
• Helps protect motors against burnout from
overloads and single-phasing when sized
properly
• Dual-element fuses can be applied in circuits
subject to temporary motor overloads
and surge currents to provide both high
performance short-circuit and overload
protection
• Offers a 10-second time delay at 5 times the
rated current
• The time-delay feature makes it possible
to use fuse amp ratings that are much
smaller than those of non-time delay
fuses. Considerable cost savings occur by
permitting the use of smaller size switches,
panels, and fuses themselves.
• Provides current limitation to help protect
downstream components from high fault
currents.
• Gives motor running back-up protection to
motors without extra costs.
