Features and Product Benefits
• The world’s first finger-safe power fuse system.
• Smallest footprint of any class fuse including Class J, CC, T and RK.
• Meets Class J time-delay electrical performance requirements.
• Available with and without open fuse indication to meet every customer
requirement.
• The indicating version features
easyI
D™ open fuse technology for faster
troubleshooting and reduced downtime.
• Faster response to damaging faults to help reduce destructive thermal and
magnetic forces.
• 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.
• High interrupting rating to safely interrupt faults up to 300kA.
• 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.
• Easy selective coordination with any other Cooper Bussmann®Low-Peak®
Class L, J and RK1 fuse with simple 2:1 amp ration between upstream and
downstream fuses.
