40A MAXI fuse for protecting compatible marine, RV, and automotive DC circuits, with a visible blown-fuse indicator that simplifies troubleshooting.

This Blue Sea Systems 5139 fuse provides 40-amp circuit protection in compatible MAXI fuse holders and fuse blocks. Tin-plated connector blades help resist corrosion in electrical environments where moisture may be present. The visible indication of a blown condition makes it easier to identify when fuse replacement is needed. It is rated for systems up to 32V DC.

40A rating: Provides circuit protection for compatible DC electrical systems.
MAXI fuse format: Fits MAXI fuse holders and MAXI fuse blocks for straightforward replacement.
Tin-plated connector blades: Help resist corrosion at the electrical connection.
Visible blown-fuse indication: Makes fault checking and maintenance easier.
1000A interrupt capacity: Supports interruption of fault current within the specified rating.

Use this replacement fuse in compatible marine, RV, automotive, and other low-voltage DC electrical applications that require a 40A MAXI fuse. Install it in a MAXI fuse holder or fuse block designed for the circuit, and match the fuse rating to the manufacturer’s specified protection requirement.

The tin-plated blades help address corrosion concerns at the connection, while the visible blown-fuse indication reduces guesswork during electrical troubleshooting. With a maximum voltage rating of 32V DC and a 1000A interrupt capacity, it is suited to properly designed low-voltage DC systems within those limits.

Confirm the required amperage, voltage, fuse format, and holder compatibility before installation. Replace a blown fuse only after identifying and correcting the underlying circuit fault.
