Description: Advanced protection, energy efficient Class RK5
dual element, current-limiting, time-delay fuses with optional
open fuse indication on select ratings.
Features:
• Provides motor overload, ground fault and short-circuit
protection
• Helps protect motors against burnout from overloads
• Helps protect motors against burnout from single-phasing
on three-phase systems
Time-delay – 10 seconds (minimum) at 500% of rated current
(8 seconds for 1⁄10-30A sizes).
• Simplifies and improves blackout prevention
(selective coordination)
• 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
• The overload element provides protection against low level
overcurrent of overloads and will hold an overload which is
five times greater than the ampere rating of the fuse for a
minimum of ten seconds.
