General Information:
• 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.
