The Marine Rated Battery Fuse (MRBF 150A) is a compact, high-amp fuse designed to provide reliable circuit protection in DC electrical systems, particularly in marine environments. Its space-saving design makes it ideal for applications with tight space constraints, such as DC main circuit protection, inverters, windlasses, and bow thrusters. Key Features:High Interrupt Rating: The MRBF offers a high interrupt rating, ensuring effective protection for large battery banks and critical components. Ignition Protected: Safe for installation aboard gasoline-powered boats, the MRBF is ignition protected, meaning it can operate safely in potentially explosive environments. Clear Window for Visual Indication: The fuse features a clear window, allowing for quick visual identification of a blown fuse. Color-Coded by Amperage: Each fuse is color-coded according to its amperage rating, facilitating easy identification and replacement. Specifications:Amperage Range: Available in ratings from 30A to 300A to suit various applications. Maximum Voltage: Rated for up to 58V DC, accommodating a wide range of DC systems. Interrupt Capacity: Capable of interrupting fault currents up to 10,000A at 14V DC, 5,000A at 32V DC, and 2,000A at 58V DC, providing robust protection against overcurrent conditions. Installation Considerations:Use with Terminal Fuse Blocks: The MRBF must be used in conjunction with appropriate terminal fuse blocks, such as Skyenergi Systems' Terminal Fuse Blocks, to ensure proper functionality and safety. Single Circuit Connection: Each fuse should be used for a single circuit connection to maintain effective protection. Proper Terminal Sizing: Ensure that ring terminals used are appropriately sized (between 3/8" (M10) and 1/2" (M12)) and that the fiber washer seats correctly inside the cable end ring terminal to prevent bypassing the fuse. By adhering to these specifications and installation guidelines, the MRBF provides a reliable and space-efficient solution for protecting DC electrical systems in marine and other demanding environments.
