400A – MEGA Fuse Style Ceramic Fuse and Holder

📝 400A – MEGA Fuse Style Ceramic Fuse and Holder

Designed for high-demand power systems, the 400A MEGA-style ceramic fuse and holder kit delivers dependable high-current circuit protection in demanding environments. Built to High Rupturing Capacity (HRC) standards, it provides fast, controlled disconnection during overloads or short circuits—protecting batteries, cabling, and critical electrical equipment.

Supplied as a matched fuse and holder set, this kit ensures correct alignment, reduced contact resistance, and long-term reliability across marine, mobile, and off-grid installations.

⭐ Essential Benefits

• High-interrupt ceramic fuse design – safely isolates faults in high-current electrical systems
• Matched fuse and holder kit – ensures secure mounting and consistent electrical contact
• Vibration-resistant centre-bolted terminals – ideal for mobile, marine, and off-road use
• High rupturing capacity – rated to interrupt up to 10kA for maximum system protection
• Excellent thermal stability – ceramic construction resists heat and electrical stress

⚙️ Functionality

• Rapid fault isolation – protects battery banks and high-load circuits from damage
• Low contact resistance – holder design minimises voltage drop and heat build-up
• Stable performance under sustained load – suitable for continuous high-current operation
