Features:
• Provides motor overload, ground fault and short-circuit
protection. When used in circuits subject to surge currents
such as those caused by motors, transformers and other
inductive components, these fuses can be sized close to
full-load amps to give maximum overcurrent protection.
• The time-delay feature makes it possible to use fuse amp
ratings which are much smaller than those of non-time delay
fuses. Considerable cost saving occurs by permitting the
use of smaller size switches, panels and fuses themselves.
• Provides a good degree of short-circuit protection (greater
current-limitation) to help protect downstream components
from high fault currents.
• Gives motor running back-up protection to motors without
extra cost.
• Helps protect motors against burnout from overloads and
single-phasing when sized properly.
• Simplifies and improves blackout prevention (selective
coordination ratios).
• 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.
