Why Choose the ABB OESAZW2 6/8-Pole Switch Mechanism?
The ABB OESAZW2, ABB product ID 1SCA022078R1600, is a dedicated 6/8-pole switch mechanism designed for compatible ABB switch-disconnectors and fuse switches, including the OT160–250 and OS32G–250 families. As part of the ABB OS/OESA accessory range, it provides a mechanical parallel attachment for combining two three-pole or two four-pole switches into a synchronised switching assembly.
The OESAZW2 uses attachment levers to mechanically connect the two compatible switches so that they operate simultaneously. Connecting two three-pole devices creates a six-pole arrangement, while connecting two four-pole devices provides an eight-pole arrangement, making the mechanism useful where additional poles must be switched together through a common operating system.
The attachment levers incorporate multiple mounting holes to accommodate different shaft distances, and compatible switch combinations can be installed horizontally or vertically. This flexibility makes the OESAZW2 suitable for industrial switchboards, machinery panels and distribution equipment requiring synchronised multi-pole switching.
Key Advantages
- Purpose-designed 6/8-pole switch mechanism for compatible ABB equipment.
- Mechanically connects two three-pole or two four-pole switches.
- Enables the connected switches to operate simultaneously.
- Supports both six-pole and eight-pole switching configurations.
- Attachment levers allow adjustment for different shaft distances.
- Supports horizontal or vertical mounting of compatible switch combinations.
Key Features
- ABB OS/OESA accessory range.
- 6/8-pole conversion mechanism.
- Parallel attachment for compatible switch-disconnectors and fuse switches.
- Connects two three-pole switches for six-pole operation.
- Connects two four-pole switches for eight-pole operation.
- Synchronised mechanical operation of both connected switches.
- Multiple attachment-lever holes for adjustable shaft spacing.
- Suitable for horizontal and vertical switch arrangements.
- ABB product group 311031-OS/OESA Accessories.
Synchronised Six- and Eight-Pole Switching
Multi-pole switching arrangements are required where more conductors need to be switched simultaneously than can be accommodated by a standard three- or four-pole device. The ABB OESAZW2 provides the mechanical connection required to combine two compatible three-pole or four-pole switches, allowing both devices to operate together through a coordinated mechanism.
The adjustable attachment arrangement gives panel builders flexibility when positioning the two switches, while support for horizontal and vertical installation helps accommodate different enclosure layouts. The OESAZW2 therefore provides a practical ABB-engineered solution for constructing compatible six-pole and eight-pole switching assemblies.
Typical Applications
- Six-pole switch-disconnector assemblies.
- Eight-pole switch-disconnector assemblies.
- Compatible ABB OT160–250 switch-disconnector installations.
- Compatible ABB OS32G–250 fuse-switch installations.
- Industrial electrical switchboards and distribution panels.
- Machinery and control systems requiring simultaneous multi-pole switching.
