Dimensional Data
General Information:
• True dual-element fuses with a minimum 10 second time-
• Long time-delay minimizes needless fuse openings due to
• Can often be sized for back-up protection against motor
• High interrupting rating to safely interrupt overcurrents up
• High degree of current-limitation due to the fast speed-of-
• Faster response to damaging short-circuit currents than
• Reduces let-through thermal and magnetic forces in order
• Proper sizing provides “no damage” Type “2” coordinated
• Dual-element fuses have lower resistance than ordinary
• Lower watts loss reduces power consumption.
• Unique dimensions assure that another class of fuse with a
