The Victron Energy CIP138225020 MEGA-Fuse is a high-current 225A, 80V DC bolt-down fuse designed to provide overcurrent protection for compatible battery and DC electrical systems. Its MEGA-format construction provides a robust and replaceable protection solution for high-current DC circuits where secure electrical connections are required.

With its 225A current rating and 80V DC voltage rating, the CIP138225020 is suitable for appropriately designed battery, inverter, charging, and DC distribution circuits. Victron Energy identifies CIP138225020 specifically as the MEGA-fuse 225A/80V model.

Package Quantity: Five (5) Victron Energy MEGA-Fuse 225A/80V fuses.

Key Technology

• 225A Current Rating
  Provides 225-amp overcurrent protection for compatible high-current DC circuits when correctly selected according to conductor ampacity and connected equipment requirements.

• 80V DC Rating
  Rated for DC circuits operating at up to 80V DC, supporting appropriately designed battery and DC power systems.

• High-Current MEGA Fuse Format
  Uses the MEGA bolt-down fuse format for robust overcurrent protection in battery feeds and other high-current DC distribution circuits.

• M8 Bolt-Down Terminals
  Features M8 terminals for secure mechanical and electrical installation within a compatible MEGA fuse holder. 

• Approx. 110mV Voltage Drop
  The 225A model is specified with an approximate 110mV voltage drop, supporting efficient integration into properly designed high-current DC circuits.

• Low Electrical Impedance
  Specified with approximately 0.235mΩ impedance, helping minimize resistive losses during normal circuit operation. 

• Replaceable Overcurrent Protection
  Provides a replaceable protective element designed to interrupt excessive current and help protect properly sized conductors and connected DC equipment.

• MEGA Fuse Holder Compatibility
  Compatible with appropriately rated MEGA fuse holders, including Victron's dedicated MEGA fuse holder and six-way MEGA fuse holder.

Best Uses

• Battery Bank Protection
  Suitable for protecting appropriately sized high-current battery conductors in compatible DC electrical systems.

• Solar & Energy Storage Systems
  Can be incorporated into properly engineered solar and battery-storage DC circuits where a 225A MEGA fuse is specified.

• 12V, 24V & Compatible 48V Systems
  The 80V DC rating supports compatible low-voltage battery systems provided the maximum circuit voltage remains within the fuse rating.

• Inverter & Inverter/Charger Circuits
  Suitable for appropriately sized high-current DC connections associated with compatible inverters and inverter/chargers.

• DC Distribution Systems
  Provides overcurrent protection for compatible high-current DC distribution circuits where system design and conductor sizing call for a 225A fuse.

• High-Current Charging Systems
  Can be used in compatible battery-charging circuits when equipment requirements and conductor sizing specify 225A overcurrent protection.
