General Information:

• Permanent replacement fuse indication.

• 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 300,000A.

• 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.

• Lower watts loss reduces power consumption.

• Unique dimensions assure that another class of fuse with a

lesser voltage rating, interrupting rating or current-Iimiting

ability cannot be substituted.

• Space-saving package for equipment down sizing.
