Parts Desk Insights
The BSS-5105 is the correct replacement fuse when a customer has a MEGA-style fuse holder and needs 200A protection — most commonly on inverter feeds, windlass circuits, or main battery cables on larger vessels. Customers should confirm their fuse holder accepts the MEGA blade format before ordering; the BSS-5187 terminal fuse is an alternative 200A option in a different physical format. For lower-current circuits, the BSS-5165 ANL fuse or BSS-5140 MAXI fuse may be more appropriate.
