OEX ACX6527 250A Bolt On Mega Fuse SF51 Type Copper Tin Plated Pack of 5

The OEX ACX6527 is a 250A bolt-on mega fuse of SF51 type, rated to 32V DC with copper tin plated contacts. Measuring 68.5mm in length with a 50.8mm centre-to-centre mounting distance, it is supplied in a pack of 5. Covered by a one-year warranty. Also available individually as the ACX6527BL.

Product overview

The ACX6527 is the highest-rated variant in the OEX SF51 mega fuse range at 250A, designed for main circuit protection on the heaviest-draw 12V and 24V electrical installations. Applications include main battery-to-distribution feeds, high-current winch systems, large multi-amplifier audio installations and heavy commercial vehicle accessory circuits where lower-rated fuses would not provide adequate protection. The bolt-on SF51 format delivers a secure, vibration-resistant connection that handles sustained high-current loads without the connection integrity concerns of lighter fuse formats.

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. The 50.8mm centre-to-centre bolt spacing is compatible with a wide range of SF51 mega fuse holders, and the single-unit version is available as ACX6527BL.
