Fusibile Schneider-MGK 757316

La serie Schneider MGK 757316 Medium-Voltage Fuse is a current-limiting fuse specially designed for motor protection in compliance with UTE standards. Le sue specifiche principali sono 7.2 kV / 160 UN / 438 mm, applicato per la protezione da cortocircuito dei circuiti motori interni a media tensione.

2. Caratteristiche del prodotto & Applicazioni
3. 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.
4. 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.
5. Indoor Installation: Adopts fiberglass housing, designed for installation in indoor power distribution cabinets or fuse compartments with reliable protection performance.
6. Alta affidabilità: 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.
7. Operazione & Installation Guidelines
8. Matching Devices: Must be used with dedicated MGK series fuse bases/brackets to ensure secure electrical connection.
9. Ambiente di installazione: Restricted to dry indoor locations; avoid exposure to humidity, dust and corrosive gases.
10. Operazione sicura: Power disconnection is mandatory during installation and replacement; insulated tools must be used to prevent electric shock hazards.
11. Maintenance Recommendation: Regularly inspect fuse appearance and connection points. Replace immediately if overheating marks or damage are found.
