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

• 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.
