Dependable Protection for Medium-Voltage Equipment
Medium-voltage fuse-links are designed to interrupt fault currents before excessive electrical energy can damage transformers, switchgear and associated equipment. The Mersen N078235 provides current-limiting protection that helps reduce the peak current and energy allowed to pass during a fault.
When correctly selected and coordinated with the protected equipment, the N078235 helps improve system safety, reduce equipment damage and minimise disruption caused by electrical faults. Its specialist rating makes it particularly suitable for low-current circuits operating at high voltages.
Typical Applications
- Medium-voltage voltage transformers.
- Auxiliary and control transformers.
- Industrial power distribution systems.
- Medium-voltage switchgear.
- Utility and infrastructure equipment.
- Specialist high-voltage electrical installations.
