OHBZX275 ABB Handle Extension for OT630–800_Y

Why Choose the ABB OHBZX275 Handle Extension?

The ABB OHBZX275 is a robust black handle extension designed to make manual operation easier on compatible ABB OT switching equipment. Identified by ABB order code 1SCA125963R1001, it belongs to ABB's OT/OETL accessories product group and is specifically intended for compatible OT630–800_Y applications.

The OHBZX275 provides additional leverage for larger switch operating mechanisms, helping operators achieve convenient manual switching on installations where the standard operating handle would otherwise provide less leverage. Its extension format is particularly useful with larger multi-pole switch configurations and demanding industrial switching applications.

With authoritative overall dimensions of 300 × 50 × 18 mm, the OHBZX275 is designed as a snap-on extension for compatible standard manual operating handles. ABB specifies a nominal handle-extension length of 275 mm, and the extension should be removed when the underlying standard handle needs to be padlocked.

Improved Leverage for Manual Switch Operation

Large switch-disconnectors and multi-pole switching assemblies can require greater operating leverage than smaller devices. A handle extension increases the effective operating length of the manual handle, helping the operator move the switch mechanism through its operating positions with improved mechanical leverage.

The ABB OHBZX275 attaches to the compatible standard manual handle using a snap-on arrangement, allowing it to be fitted when additional leverage is required and removed when necessary. For installations where the standard handle is to be padlocked, the extension is removed before applying the padlock to the underlying handle.

Typical Applications

• ABB OT630–800_Y switching installations.
• Large manual switch-disconnector assemblies.
• Bypass and transfer switching equipment.
• Multi-pole industrial switching applications.
