- Caractéristiques du produit & Applications
- Dedicated Motor Protection: Optimized for short-circuit protection of 7.2 kV medium-voltage motors, effectively preventing motor damage caused by dynamic and thermal effects of short-circuit current.
- Current-Limiting Technology: Cuts off the circuit rapidly before short-circuit current reaches its peak, reducing fault energy release and protecting motor windings and insulation systems.
- Indoor Installation: Adopts fiberglass housing, designed for installation in indoor power distribution cabinets or fuse compartments with reliable protection performance.
- Haute fiabilité: Built on Schneider medium-voltage fuse technology platform, meeting long-term stable operation requirements for industrial environments and compatible with various medium-voltage motor control solutions.
- Opération & Directives d'installation
- Appareils correspondants: Must be used with dedicated MGK series fuse bases/brackets to ensure secure electrical connection.
- Environnement d'installation: Restricted to dry indoor locations; avoid exposure to humidity, poussières et gaz corrosifs.
- Fonctionnement sûr: Power disconnection is mandatory during installation and replacement; insulated tools must be used to prevent electric shock hazards.
- Maintenance Recommendation: Regularly inspect fuse appearance and connection points. Replace immediately if overheating marks or damage are found.
