Product Details:

Bussmann Low-Peak® CubeFuse® Class J Finger-Safe branch circuit rated fuse comes with an element window to visually inspect blown element. It operates at a voltage rating of 600 VAC/300 VDC, current rating of 70 Amps and an interrupt current rating of 300 kilo-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 3.010 Inch. Dual-element fuse can be used as a time-delay or a slow-blow fuse making it economical.

Low voltage 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. It 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.
