Reliable Short-Circuit Protection for Motor Circuits
aM fuse links are designed specifically for motor circuit applications, where temporary high currents occur during motor starting. Their operating characteristics allow these normal starting currents while providing rapid interruption when a damaging short-circuit current occurs.
Because an aM fuse is intended primarily for short-circuit protection, the ABB E9F22AM50 is normally coordinated with a suitable overload protective device. This arrangement provides comprehensive motor circuit protection while allowing the motor to start and operate without unnecessary fuse operation.
Typical Applications
- Industrial motor circuits.
- Motor starters and control equipment.
- Pumps, fans and compressor systems.
- Conveyors and material handling machinery.
- Industrial automation and machinery control panels.
- OEM motor-control assemblies and production equipment.
