TCF20

The TCF20 is a 20A Low-Peak CUBEFuse finger-safe dual-element time-delay class CF Indicating Fuse with Glass filled PES case and electroless tin plated copper alloy terminal. It is the worlds first finger-safe power fuse system. It meets class CF and Class J time-delay electrical performance requirements. The indicating version features easy ID™ 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. Provides type 2 No Damage protection for IEC motors starters when properly sized. Easy selective coordination with any other Cooper Bussmann low-peak class CC, L, J and RK1 fuse with simple 2:1 amp ration between upstream and downstream fuses.

• 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
