Allen-Bradley 1492-FB2J30-L 2-Pole Fuse Holder

The Allen-Bradley 1492-FB2J30-L is a dead-front, two-pole, rail-mount fuse holder designed to protect control-panel circuits by housing Class J fuses rated up to 30 A and 600 V (AC/DC). The -L variant adds a blown-fuse indicator for quick status checks, and the enclosure depth is 70 mm, making it suitable for compact panel layouts. This model is CSA-listed and part of Rockwell Automation's 1492-FB fuse-holder family, which supports multiple-pole configurations with and without indication to fit different maintenance needs. Each of the two poles accepts a Class J fuse, enabling reliable fault isolation in 600 V systems typical of industrial automation. The dead-front design conceals the fuse block from view when mounted, reducing wiring exposure and providing a clean panel appearance while maintaining straightforward access for fuse replacement. The 1492-FB family is widely used in control panels for motor starters, conveyors, and other automation equipment, where clear fuse status and robust mounting are essential.
