The Victron Energy CIP138200020 MEGA-Fuse is a high-current 200A, 80V DC bolt-down fuse designed to provide overcurrent protection for compatible battery and DC electrical systems. Its MEGA-format construction provides a robust, replaceable protection solution for high-current DC circuits where secure fuse connections are required.

With its 200A current rating and 80V DC voltage rating, the CIP138200020 is suitable for appropriately designed battery, inverter, charging, and DC distribution circuits. Victron Energy's current product documentation confirms the specific 200A/80V rating and CIP138200020 part number. 

Package Quantity: Five (5) Victron Energy MEGA-Fuse 200A/80V fuses.

Key Technology

• 200A Current Rating
  Provides 200-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 low-voltage battery and DC power systems.

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

• M8 Bolt-Down Connection
  Features an M8 mounting interface for secure mechanical and electrical installation in a compatible MEGA fuse holder.

• Approx. 110mV Voltage Drop
  The 200A version is specified with an approximate 110mV voltage drop for integration into appropriately designed high-current DC circuits.

• Low Cold Resistance
  The fuse is specified with approximately 0.253mΩ cold resistance, helping limit 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
  Designed for installation in an appropriately rated MEGA fuse holder, including compatible Victron Energy fuse-holder solutions.

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 200A MEGA fuse is specified.

• 12V, 24V & 48V Systems
  The 80V DC rating supports compatible nominal 12V, 24V, and 48V 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 calls for a 200A fuse.

• High-Current Charging Systems
  Can be used in compatible charging and battery circuits when the equipment manufacturer and conductor sizing specify 200A overcurrent protection.
