Why Choose the ABB OS125GD03HP 125 A DIN Switch Fuse?
The ABB OS125GD03HP is a 125 A, 3-pole, front-operated DIN switch fuse designed for switching, isolation and fuse protection in demanding low-voltage distribution systems. Part of the ABB OS range, it is designed for DIN NH000/NH00 fuse links and combines robust switch-disconnector construction with fuse-based circuit protection.
The defining feature of the OS125GD03HP is its extra-heavy silver treatment. The HP version uses an approximately 20 µm silver coating on conductive metal parts, providing enhanced contact-surface treatment for demanding applications. The operating mechanism is positioned on the left side.
The OS125GD03HP is rated at 125 A and 690 V AC, with a 1000 V insulation voltage. Its three-pole, base-mounted configuration and DIN fuse compatibility make it suitable for industrial switchboards, machinery feeders and low-voltage power-distribution assemblies.

DIN Fuse Switching with Extra-Heavy Silver Treatment
The ABB OS125GD03HP combines manual switching and isolation with DIN fuse-based overcurrent protection across three poles. Compatibility with NH000 and NH00 fuse links makes the unit suitable for a broad range of industrial feeder and distribution applications requiring standardised DIN fuse protection.
The HP special-treatment version uses an extra-heavy approximately 20 µm silver coating on conductive metal parts. Combined with its 125 A rating, front operation and left-side mechanism, this makes the OS125GD03HP a purpose-designed switch fuse for demanding industrial electrical installations.
Typical Applications
- Industrial low-voltage power distribution.
- Electrical switchboards and distribution panels.
- DIN NH000 and NH00 fused circuits.
- Machinery supply isolation and protection.
- Industrial motor and equipment feeders.
- Applications requiring enhanced silver treatment of conductive parts.
