Product Details

Size: 1 Inch x 2.130 Inch

Selective coordination ratio of 2:1 (within low-peak fuse family) prevents electrical shutdowns from extending beyond the failed circuit

The indicating version features open fuse technology for faster troubleshooting and reduced downtime

No venting of arc or molten metal and gases during opening

Robust cycling and inrush current withstand

Low let through currents under fault conditions

Detailed Description: Bussmann Low-Peak® Class J Finger-Safe fuse operates at a voltage rating of 600 VAC/300 VDC and current rating of 40 Amps. It features dual-element construction with a minimum of 10 seconds time-delay at 500% of rated current providing ultimate protection. The long time-delay fuse reduces circuit openings due to temporary overloads and transient surges. It measures 1 Inch x 2.130 Inch. Dual-element fuse can be used as a time-delay or a slow-blow fuse making it economical.

Fuse provides a faster response to minimize destructive thermal and magnetic forces. Fuse offers low watt loss power consumption and has robust cycling that can withstand inrush current. It is suitable for branch circuit disconnect and branch circuit protection. Low voltage fuse finds application in electrical panelboards, industrial control, machinery disconnects and required finger safe systems. Finger-Safe fuse is UL listed/CSA certified/CE compliant and meets IEC requirements.
