MRBF Series Current Fuses — Key Benefits and Features Wide range of ratings: Available in 50A, 60A, 75A, 80A, 90A, 100A, 125A, 150A, 175A, 200A, 250A, 300A, and 400A to match different circuit requirements and simplify inventory management. Ready-to-install 60A kit: The 60A option is supplied as a specific holder-and-fuse combination, so you receive both the fuse and its compatible holder together for straightforward installation. Purpose and protection: MRBF fuses are designed to interrupt excessive current and protect conductors and equipment from overloads and short circuits. Handles significant electrical loads: These fuses are intended for circuits with high current demands, helping maintain safe operation under heavy load conditions. Reliable performance: Standardized ratings and a dedicated holder option promote consistent, predictable protection across applications. Compatibility and convenience: The included holder with the 60A option ensures a correct mechanical and electrical fit without the need to source a separate holder. Application flexibility: The range of amperages supports power distribution, motor protection, and other industrial or commercial electrical circuits. Typical use scenarios Small commercial or light industrial distribution panels: Select the appropriate MRBF rating to protect feeder circuits or subpanels from overloads. Motor circuits and equipment protection: Use MRBF fuses to safeguard motors or control equipment that draw high starting and running currents. Renewable or energy-storage installations and inverter inputs: Employ the correct MRBF rating to protect high-current DC or AC circuits where reliable overcurrent protection is needed. What to expect Function: Overcurrent interruption to protect wiring and equipment. Size/option note: A 60A variant is offered as a complete holder-plus-fuse package for immediate use. Performance: Built for higher-current applications and consistent, reliable protection across the listed amperage options. Choose the MRBF series when you need standardized, high-current fuses with a broad selection of ratings and a convenient 60A holder-and-fuse option for quick installation.
