Fast-acting ATO/ATC fuse for 40-amp circuit protection in automotive, RV, and marine electrical systems.

This Blue Sea Systems fuse provides standard blade-style protection for compatible circuits in automobiles, trucks, boats, and recreational vehicles. Its fast-acting design helps protect electronic devices, while tin-plated connector blades resist corrosion in damp operating environments. A visible indicator makes a blown fuse easier to identify, and each package includes two fuses.

40A rating: Provides circuit protection for compatible 40-amp applications.
ATO/ATC format: Fits compatible standard automotive-style fuse blocks and panels.
Fast-acting construction: Responds quickly to overcurrent conditions to help protect electronic devices.
Tin-plated connector blades: Help resist corrosion in marine, RV, and automotive environments.
Visible blown-fuse indication: Makes inspection and replacement easier.
Two-fuse package: Includes a replacement fuse for convenient service readiness.

Use the Blue Sea Systems 5246 as a replacement fuse in compatible ATO/ATC fuse blocks, fused switch panels, and other standard blade-fuse applications. The 40-amp rating is suited to circuits specified for that capacity; always match the replacement fuse to the equipment manufacturer’s requirements.

Its fast-acting format is intended for electronic-device protection, while the tin-plated blades help limit corrosion at the electrical connection. The visible indicator supports quick troubleshooting when a circuit stops operating. With two fuses in the package, one can be installed while the second remains available as a spare for routine vehicle, boat, or RV maintenance.
