Why Choose the ABB OFAF000AM6 6A 500V HRC DIN aM Fuse Link?
The ABB OFAF000AM6 is a compact and dependable 6 A HRC DIN aM fuse link designed for short-circuit protection in motor circuits and industrial electrical equipment. As part of the ABB OFAF fuse link range, it combines high rupturing capacity protection with a standardised NH000 format for integration into compatible industrial fusegear.
The OFAF000AM6 uses the aM utilisation category, specifically intended for motor-circuit short-circuit protection. This partial-range characteristic accommodates the temporary high currents associated with motor starting while providing effective fault protection when coordinated with suitable overload protection.
With a rated current of 6 A, a rated voltage of 500 V AC and an NH000 / DIN size 000 format, the OFAF000AM6 is well suited to compact motor-control installations. The fuse link also incorporates dual indication, helping maintenance personnel identify fuse operation during inspection and fault finding.
