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 amp rating of the
fuse for a minimum of ten seconds.
