Pacer Marine Rated Battery Fuses (MRBF) provide reliable high-current circuit protection for large marine battery banks and demanding DC applications. Designed to install directly onto compatible MRBF fuse blocks, these fuses help protect main battery, inverter, windlass, and bow thruster circuits from short circuits and overcurrent conditions. Ignition-protected and rated for systems up to 58 VDC, they deliver dependable protection in enclosed marine environments. Available in ratings from 30A to 300A, MRBF fuses offer a compact, space-saving solution for high-amperage circuit protection.

Characteristics:

  • Compact, high-amp fuse protection—appropriate for DC main, inverter, windlass, and bow thruster circuit protection.
  • Single and dual fuse block options offer flexibility to deploy multiple circuits in a compact space.
  • Interrupt rating satisfies ABYC requirements for DC main circuit protection on many large battery banks.
  • Ignition-protected safe for installation in closed compartments with potential explosive gases.
  • Transparent window, visual indication of blown condition.
  • Mounts conveniently on XD Relay I/O terminals, battery terminals, and high ampere busbar terminals.

Features:

  • Protects electrical circuits from short-circuit events and over-current loads, preventing wire insulation overheating and subsequent destruction.
  • Ignition protected: Safe for installation in enclosed spaces on board gasoline engine-powered boats or in enclosed battery compartments.
  • Bullet-proof construction: Weatherproof high-temp materials for engine compartment applications and solid mounting points.
