Eaton Bussmann MRBF-250 Marine Rated Battery Fuse, 250A 58V DC, Ignition Protected High-Current - Pack of 5

MRBF Series Marine Rated Battery Fuse - Eaton Bussmann Series

The Eaton Bussmann MRBF-250 is a high-performance Marine Rated Battery Fuse engineered for heavy-duty DC circuit protection. Designed to handle 250 Amps at a maximum voltage of 58V DC, this fuse provides a rugged and space-efficient solution for protecting main battery circuits. It features high interrupting ratings to safely manage short-circuit events from large battery banks. The MRBF series is ignition-protected as per SAE J1171 standards, permitting safe installation in gasoline-powered engine compartments. Its design minimizes the number of connections required by mounting directly to battery terminals or power buses when used with compatible MRBF fuse blocks.
