Why Choose the ABB OFAZ3A3-HV 3-Pole 630 A Fuse Base?
The ABB OFAZ3A3-HV is a robust 3-pole DIN NH fuse base designed for high-voltage low-voltage distribution applications requiring reliable mounting and connection of NH fuse links. Part of the ABB OFAZ-HV fuse base series, this open-format model is rated at 630 A and supports operation at up to 1000 V AC/DC.
Designed for NH size 2 and size 3 fuse links, the OFAZ3A3-HV provides a three-pole platform for industrial switchboards, power-distribution panels and high-voltage AC fusegear. Its open construction is rated IP00, making it suitable for installation within appropriately protected electrical enclosures.
The OFAZ3A3-HV is engineered for continuous-duty operation and supports both vertical and horizontal mounting. With a 35 mm terminal width, a maximum permitted fuse power dissipation of 60 W and an ambient operating range of -25 to +55 °C, it provides a practical solution for demanding industrial fuse protection systems.

Reliable NH Fuse Mounting for High-Voltage Distribution
Fuse bases provide the mechanical support and electrical connection required between replaceable NH fuse links and the distribution circuit. The ABB OFAZ3A3-HV is designed specifically for demanding applications requiring 1000 V capability and supports NH size 2 and size 3 fuse links with a rated operational current of 630 A.
Its three-pole configuration allows all three phases of a three-phase circuit to be accommodated within one assembly. The open IP00 construction is intended for installation within suitable switchboards or enclosures, while the ability to mount the fuse base vertically or horizontally provides flexibility when designing industrial distribution equipment.
Typical Applications
- Industrial three-phase power distribution.
- Electrical switchboards and distribution panels.
- High-voltage AC fusegear assemblies.
- NH2 and NH3 fuse-link installations.
- Industrial power conversion and inverter systems.
- Commercial and industrial low-voltage electrical installations.
