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, hence they run cooler.
Dimensions (inches)
• 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.
• Space-saving package for equipment down sizing.
