Reliable Protection for Medium Voltage Motors
Motor protection back-up fuse-links are designed to interrupt severe short-circuit currents rapidly while tolerating the repeated inrush currents generated during motor starting. Their current-limiting characteristics reduce the peak current and fault energy imposed on motors, cables, contactors and associated switchgear.
The Mersen R075524 combines a high breaking capacity with motor-specific operating characteristics and an integrated striker. When the fuse-link operates, the striker can provide fault indication or activate compatible switching equipment, supporting coordinated isolation and safer maintenance.
Typical Applications
- Medium voltage electric motors.
- Industrial motor control centres.
- Pump and compressor installations.
- Mining and quarrying equipment.
- Water and wastewater treatment plants.
- Power generation facilities.
- High voltage motor starters.
- OEM medium voltage switchgear.
