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
