Product overview
The ACX6523 is the 150A variant in the OEX SF51 mega fuse range, providing higher-current main circuit protection for demanding 12V and 24V automotive, caravan and marine electrical installations. The bolt-on SF51 format delivers a secure, vibration-resistant connection suited to high-draw applications including large amplifier main feeds, dual battery system protection, winch circuits and heavy commercial accessory installations. Copper tin plated contacts provide reliable conductivity and oxidation resistance across the service life of the fuse.
The pack of 5 suits workshop, trade and owner-installer use where having spare fuses readily available alongside the installed unit is practical. The 50.8mm centre-to-centre bolt spacing is compatible with a wide range of SF51 mega fuse holders. The single-unit version is available as ACX6523BL.
