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.
