MEGA-fuse 100A/32V — is a reliable fusible link designed to protect direct current (DC) electrical networks within Victron Energy equipment. The part guarantees a high level of safety, instantly breaking the circuit in the event of a short circuit or dangerous overloads in systems with a current up to 100 amps and an operating voltage of no more than 32 V (suitable for 12V and 24V).
An excellent solution for de-energizing inverter systems, charging units, DC busbars, and battery assemblies, where lightning-fast response to current anomalies and extremely low conductor resistance are required.
Main Advantages of the MEGA-fuse Insert
- Operating current: 100 A, peak voltage up to 32 VDC
- Minimal internal resistance: 0.6 mOhm, completely eliminating unnecessary energy losses
- Voltage drop: only 90 mV, ensuring high operational efficiency
- Instant triggering during short circuits
- Universal MEGA standard — full compatibility with any standard holders
- Small dimensions and ease of installation
- Official Victron Energy certification — flawless operation in conjunction with branded components
Technical Nuances
- Fusible element — blows when the current exceeds acceptable limits, protecting wiring, electronics, and batteries from burning out.
- Low cold resistance (0.6 mOhm) — ideal for use in networks with high starting currents
- High selectivity — allows for proper configuration of cascaded protection in complex electrical installations
Areas of Application
• Ensuring battery safety in 12/24 Volt networks
• Protecting inverters from Victron (MultiPlus, Quattro lines)
• Safeguarding main cables and direct current busbars
• Marine electrical systems requiring compact and fault-tolerant solutions
• Motorhomes — insurance for energy-intensive consumers
