Dimensional Data
LP-CC
General Information:
LP-CC LOW-PEAK Yellow™ Fuse
• A superior all-purpose, space-saving branch circuit fuse
that meets most protection requirements up to 30 amps.
• Very compact; physical size is only
⁄‹Ω£™∑ ≈ 1⁄Ω™∑
(10.3mm
≈
38.1mm) with rejection tip.
• The unique yellow color makes it easy to tell that the correct
fuse type is installed.
• Faster response to damaging short-circuit currents and
higher interrupting rating than mechanical overcurrent
protective devices.
200,000 Ampere Interrupting Rating
• Maximum interrupting rating for available fault current in
today's large capacity systems.
• Helps ensure that future growth will not obsolete the system.
Dual Characteristics
• Time-delay to avoid unwanted fuse openings from surge
currents.
• Fast speed of response under short-circuit conditions for a
high degree of current-limitation.
•
ADVANTAGE:
The LOW-PEAK
®
fuse can be sized close
to full load ratings for maximum overload and short-circuit
protection.
•
ADVANTAGE:
Can be used where either a time-delay or
a fast-acting fuse is needed, making selection easier and
reducing spare fuse inventories for substantial cost reduction.
Superior Motor Protection
• For protection of small horsepower motor circuits.
• Proper sizing can provide Type “2” coordinated protection
for NEMA and IEC motor controllers.
• Motors receive maximum protection against burnout from
overloads and single phasing.
