Features
True dual-element fuses with a minimum 10 second
time-delay at 500% overload.
Long time-delay minimizes needless fuse openings due
to temporary overloads and transient surges.
Can often be sized for back-up protection against motor
burnout from overload or single-phasing if other
overload protective devices fail.
High interrupting rating to safely interrupt overcurrents
up to 300kA (self certified).
High degree of current limitation due to the fast
speed-of-response to short-circuits.
Faster response to damaging short-circuit currents than
mechanical overcurrent protective devices.
Reduces let-through thermal and magnetic forces in
order to protect low withstand rated components.
Proper sizing provides “No Damage” Type “2”
coordinated protection for NEMA and IEC motor control
in accordance with IEC Standard 947-4-1.
Dual-element fuses have lower resistance than ordinary
fuses so they run cooler.
Lower watts loss reduces power consumption.
Unique dimensions assure that another class of fuse
with a lesser voltage rating, interrupting rating or
current-limiting ability cannot be substituted.
