JL Audio XD-FDBU-2 2-Way MAXI Fused Distribution Block - #90461

The JL Audio XD-FDBU-2, Designed to split a large wire down to two smaller wires where fusing of the small wires is needed. The input of this block accepts wire from 1/0 to 4 AWG, while the two fused outputs each accept wire from 4 AWG to 8 AWG. OmniSert receptacles capture various size wires without the need for adaptor sleeves.

Forged and machined brass construction with marine-grade stannum plating. A high-temperature polycarbonate base and cover provide insulation and protection. Requires two MAXI Fuses, appropriately rated for the equipment being connected. These are sold separately. Fuses can be pulled and inserted without removing the cover.

OmniSert (Patent Pending)

This unique block terminal design results in better mechanical and electrical contact between the wire and the block. Conventional captured wire block designs use a narrow screw that only contacts the center of the inserted wire. When tightened, the screw digs a depression into the wire and only applies full pressure in a relatively small contact patch. Additionally, when smaller wires are inserted into the block, the screw does a poor job of gripping the smaller wire, increasing the possibility of an unreliable connection.

JL Audio’s patent-pending OmniSert technology uses a large diameter screw with a domed contact area that precisely matches the contour of the wire bore. This oversized domed surface evenly applies pressure to the wire over a larger contact area in the body of the block. The design also does an excellent job of capturing smaller wires in the block, eliminating the need for ferrules or sleeves to achieve proper mechanical integrity.
