Dimensions - in  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.
* Permits the use of smaller and less costly switches. 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 higher degree of short-circuit protection (greater
current-limitation) in circuits in which surge currents or temporary overloads
occur.
* Helps protect motors against burnout from overloads
* Gives motor running back-up protection to motors without extra costs
* Helps protect motors against burnout from single phasing on three phase
systems
* 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 amp
rating of the fuse for a minimum of ten seconds
