High voltage fuse
ETI
General information
ETI HV fuse-links named VV THERMO are designed to protect devices in switch-gears and other equipment (distribution transformers, capacitors, motors) from thermal and dynamic effects of shortcircuits and overcurrents. Time-current characteristics correspond to standard IEC 60282-1, item 3.3.3. Back-up fuse.
They are suitable for installation in:
- indoor and outdoor switchgear
- gas (SF6)-insulated enclosures
- special service conditions (different from normal conditions, described in item 2.1. of standard IEC 60282-1)
The most significant features of ETI high voltage fuses:
- Low temperature rise bacause of low power dissipation
- High breaking capacity 50 kA
- Possibility of three different striker pin forces: 80 N and 120 N (with integrated temperature dependent limiter) and 50 N.
- Reliable sealing system against humidity irruption
- Low switching voltages
- Upon a request, fuse links can be supplied into no-standard dimensions
