Reliable Short-Circuit Protection for Motor Circuits
aM fuse links are partial-range protective devices developed specifically for motor circuits. They provide protection against short-circuit currents while accommodating the temporary elevated currents associated with motor starting, with overload protection normally supplied by a separate coordinated motor protection device.
The ABB OFAF000AM4 combines a 4 A current rating, operation at up to 500 V and compact DIN size 000 construction, making it suitable for integration into compatible industrial fusegear and motor control systems.
Typical Applications
- Industrial motor feeders and motor circuits.
- Motor starters and contactor assemblies.
- Motor control centres.
- Industrial machinery and automation panels.
- Compatible DIN fuse bases and switch-fuse equipment.
- Short-circuit protection of motor circuits.
