General Information:
TRON
®
HRC FORM II Class C Fuses
• TRON
®
HRCII-C fuses are designed to withstand inrush
currents on typical motor start-ups while offering high
current limitation in the short-circuit region.
• The TRON
®
HRCII-C fuses can be sized close to the motor
nameplate rating.
• Closer protection is offered for many motor sizes with the
availability of these additional fuse ratings.
• TRON
®
HRCII-C fuses have a high degree of current-limitation
greatly reducing the magnetic forces and thermal stresses
produced in today’s high capacity systems.
• TRON
®
HRCII-C fuses have an interrupting rating of 200,000
RMS symmetrical amperes at 600 volts.
• TRON
®
HRCII-C fuses are dimensionally interchangeable with
other Form II fuses on the market and can be used with the
same confidence as other High Quality Buss Fuses.
