Product Information

Master ANL Fuse Block for 4 AWG - 1/0 AWG Wire (250A Maximum)

This amazingly flexible Master Fuse Block is easy to install and is designed to protect larger power wires that feed multiple amplifiers or an entire system.

Each wire connection block is capable of rotating to five different wire-entry angles, giving you maximum power wire routing flexibility. This really comes in handy when working with larger power wires, which can be tricky to manage in a crowded engine or battery compartment.

OmniSert™ captured-wire receptacles accept various size wires from 4 AWG to 1/0 AWG, 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.

Cover must be removed (no tools required), and a flat-blade screwdriver (or large coin) must be used to pull or insert the fuse.

Requires one ANL Blade Fuse, appropriately rated for the equipment being connected.  These are sold separately.
