GigaFuse is the world’s only hermetically sealed electromechanical fuse designed for high-voltage and high-power fuse application requirements.
The GigaFuse is a bi-directional device capable of handling system voltages up to 1000V and features both passive and active triggering options. This new design significantly reduces system resistance, eliminates thermal aging, and significantly reduces installation time, system complexity, and cost.
Features
- Functional Safety: Passive technology with electromechanical release mechanism
- Fast disconnect: <3ms clear time independent from current level
- System protection coordination: tunable trip current to easily pair with HV contactors
- Optional active control: to provide designers flexibility in active/passive protection methods
- Up to 10MW interrupt capability
- 400A continuous current carry (4/0 busbars); consult engineering for higher current
