• The world’s first finger safe industrial fuse system.
• True dual-element fuse construction with a minimum of 10
seconds time-delay at 500% of rating.
• Long time-delay minimizes nuisance circuit openings due
to temporary overloads and transient surges.
• Meets UL Class J Time-Delay electrical performance
requirements.
• High interruption rating to safely interrupt faults up to
300,000A.
• Faster response to damaging faults reduces destructive
thermal and magnetic forces.
• Permanent open fuse indication.
• Designed to be an internationally accepted and specified
world class product.
• Smallest footprint of any power class fuse including Class
J, CC, T and RK.
• Meets requirements of IEC 60529 for IP-20 finger safe
rating.
• No venting of arc or molten metal and gases during
opening.
• Robust cycling and inrush current withstand.
• Low let through currents under fault conditions.
• Provides TYPE 2 “no damage” protection for IEC motors
starters when properly sized.
• Low watt loss reduces power consumption and lowers
operating temperature.
• Conventional Class J fuse case sizes and ampere ratings.
• Dovetail fuseholder design for ganging multiple fuse
poles.
• 30, 60 and100A fuseholders can be ganged together.
• 30A fuses can be plugged into the 60 and 100A holder
without a reducer.
• 60A fuses can be plugged intothe 100A holder without
a reducer.
• 35mm DIN rail and chassis mounting features.
• Fuseholder wire ports rated for dual wires.
