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.
