    Tough environments need a tougher fuse.

    When you need to protect the electrical circuits of a ship and other large marine vessels, you need a fuse that’s designed for the job. Marine fuse blocks are built specifically to withstand the sometimes unpredictable conditions of being at sea. Used across all types of large scale marine applications, marine fuse blocks carry interruption ratings of 10,000A, with currents ratings ranging anywhere from 30A to 300A. Common applications for marine fuse blocks include alternator outputs, accessory circuits, starter motor inputs, switching, and power control.

    The perfect fit for your marine fuse panel.

    Safety and reliability are always the most important aspects of any electrical system, but those qualities are that much more important when you’re at sea. Constructed with ceramic housing and ring terminals made of thermoplastic (a material which become plastic when heated and subsequently hardens when cooled), marine fuse blocks are built to withstand even the harshest environments. Another advantage of marine fuse blocks are their size. When you’re on a ship space is often at a premium, so marine fuse blocks are designed to fit in even the tightest spaces.
