Reliable Motor Circuit Protection
The Mersen FR10AM40V12P is designed to protect motors, motor starters, contactors and associated switchgear from destructive short-circuit currents. Its aM characteristic allows the normal high inrush current during motor starting whilst providing rapid interruption of dangerous fault currents before equipment damage can occur.
The integrated striker extends automatically when the fuse operates, allowing compatible fuse holders to activate auxiliary contacts for remote indication, alarm signalling or machine shutdown, helping maintenance engineers quickly identify and rectify faults.
Typical Applications
- Motor starter protection.
- Motor control centres (MCCs).
- Industrial control panels.
- Machine building and OEM equipment.
- Industrial switchgear.
- Automation and production machinery.
