ABB OFAF000H63 is a 63 A gG HRC DIN size 000 fuse link rated at 500 V AC and 250 V DC with dual indication for reliable overload and short-circuit protection.
Why Choose the ABB OFAF000H63 63A DIN 43620 Size 000 Fuse?
The ABB OFAF000H63 is a 63 A HRC DIN fuse link designed for dependable protection of low-voltage electrical circuits. Part of ABB's OFAF range of universal fuse links, it combines a compact DIN size 000 / NH000 format with a full-range gG characteristic for industrial power distribution, machinery and control applications.
The OFAF000H63 uses the gG utilisation category, providing full-range protection against overload and short-circuit currents. Its standardised DIN blade construction enables integration with compatible fuse bases, fuse switches and switch-disconnectors used throughout industrial and commercial electrical installations.
With a rated current of 63 A and rated voltage of 500 V AC / 250 V DC, the OFAF000H63 delivers substantial circuit protection in the compact NH000 format. It also features dual indication and has a power loss of approximately 4.7 W at rated current.

Reliable Full-Range Protection for Electrical Circuits
gG fuse links such as the ABB OFAF000H63 provide full-range protection by responding to both overload and short-circuit conditions. When excessive current causes the fuse element to operate, the fuse interrupts the circuit to help protect cables, conductors and connected electrical equipment from the effects of damaging fault currents.
The OFAF000H63 combines a 63 A rating with compact DIN size 000 construction, making it suitable for space-conscious industrial fusegear. Its standardised DIN blade format supports installation in compatible fuse bases and switching equipment used in distribution panels, machinery and industrial control systems.
