Features:
• Provides motor overload, ground fault and
short-circuit protection
• Helps protect motors against burnout from
overloads and single-phasing when sized
properly
• 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 on inrush current which is five times
greater than the amp rating of the fuse for a
minimum of ten seconds
