Why Choose the ABB OFAF2H315 315 A HRC Fuse Link?
The ABB OFAF2H315 is a high-performance 315 A HRC fuse link designed to provide dependable overcurrent and short-circuit protection in industrial low-voltage electrical distribution systems. Part of ABB's OFAF range of DIN-type fuse links, this model combines a DIN size 2 / NH2 format with a gG utilisation category for general-purpose protection of cables, conductors and electrical equipment.
Designed for industrial power distribution, switchgear and fuse-switch applications, the OFAF2H315 has a rated voltage of 500 V and complies with IEC 60269 requirements. The gG operating class provides full-range protection against both overload and short-circuit currents, making the fuse suitable for a wide variety of electrical distribution applications.
With a rated current of 315 A, the OFAF2H315 uses the standard NH2 / DIN size 2 blade-contact format for installation in compatible fuse bases, fuse switches and switch-disconnectors. ABB's OFAF_H_ range also incorporates dual fuse-status indication on size 2 fuse links, helping maintenance personnel identify an operated fuse during inspection.

Reliable Protection for Low-Voltage Distribution Systems
HRC fuse links protect electrical circuits by interrupting excessive current before conductors and connected equipment can be damaged. The ABB OFAF2H315 uses a gG characteristic to provide full-range protection against overload and short-circuit conditions in industrial low-voltage distribution circuits.
The standardised NH2 blade format enables the fuse link to be used with appropriately rated DIN fuse bases, fuse switches and fuse-switch disconnectors. Its robust HRC construction makes it particularly suitable for switchboards, distribution panels and industrial power systems where dependable fault interruption is essential.
Typical Applications
- Industrial low-voltage power distribution.
- Electrical switchboards and distribution panels.
- Fuse-switch disconnectors and fuse bases.
- Cable and conductor protection.
- Industrial machinery power circuits.
- Commercial and industrial electrical installations.
