•
The worldÕs 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.
•
Time-delay characteristic allows for back-up protection
against motor burnout from overload or single phasing if
other overload device fails.
•
Meets UL Class J Time-Delay electrical performance
requirements.
•
High interruption rating to safely interrupt faults up to
300,000 amperes.
•
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 Òno damageÓ 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 and 60 Amp fuseholders can be ganged together.
•
30 Amp fuses can be plugged into the 60A holder without a
reducer.
•
35mm DIN rail and chassis mounting features.
•
Fuseholder wire ports rated for dual wires.
