Fast-acting 7.5A ATO/ATC fuse for protecting electronic devices and vehicle circuits, with corrosion-resistant blades and visible blown-fuse indication.

The Blue Sea Systems 5240 is a 7.5A ATO/ATC fuse for standard automotive, truck, and marine electrical applications. Its fast-acting design helps protect electronic devices and other circuits from excessive current. Tin-plated connector blades resist corrosion, while the visible element makes a blown fuse easy to identify. Each package contains two fuses.

7.5A rating: Provides the specified current protection for compatible circuits.
ATO/ATC format: Fits fuse holders and blocks designed for standard ATO/ATC fuses.
Fast-acting construction: Responds quickly to overcurrent conditions in electronic-device circuits.
Tin-plated connector blades: Help resist corrosion in vehicle and marine electrical environments.
Visible blown-fuse indication: Makes inspection and replacement easier.
Two-fuse package: Provides a spare for maintenance or replacement.

The Blue Sea Systems 5240 supports circuit protection in automotive, truck, boating, and other low-voltage electrical systems that use ATO/ATC fuse holders. Install it in a compatible fuse block or holder with the circuit de-energized, and match the 7.5A rating to the equipment manufacturer’s specified protection requirement. The fast-acting fuse is suited to electronic devices and standard branch circuits where rapid overcurrent protection is needed. Its tin-plated blades help limit corrosion at the electrical connection, while the visible element allows a quick visual check when a circuit stops operating. Keep the second fuse available as a replacement for routine onboard, vehicle, or workshop service.
