OTZS2/B10 ABB Shaft Locking Ring and Grub Screw Set, Pack of 10

Why Choose the ABB OTZS2/B10 Shaft Locking Ring & Grub Screw Set?

The ABB OTZS2/B10 is a 10-piece shaft locking ring and grub screw accessory set for compatible ABB switching equipment. Identified by ABB product reference 1SCA126043R1001, it provides the hardware required for securing compatible operating shafts in switch-disconnector installations.

Each locking arrangement combines a shaft locking ring with a grub screw, providing a simple mechanical means of retaining the operating shaft in the required position. This makes the OTZS2/B10 useful for switch assembly, panel building, servicing and replacement work where the specified ABB shaft-locking hardware is required.

Supplied as a pack of 10, the OTZS2/B10 is specified for compatible ABB equipment in the 32–OS250B range. The multi-piece pack is particularly practical for panel builders, maintenance teams and production environments working with multiple compatible ABB switching assemblies.

Secure Shaft Retention for ABB Switching Assemblies

Operating shafts transfer mechanical movement between a switch mechanism and its operating arrangement. Suitable locking hardware helps retain the shaft in its intended position so that the mechanical operating assembly remains correctly configured.

The ABB OTZS2/B10 provides the required locking ring and grub screw combination in a convenient 10-piece format for compatible equipment. It is therefore suitable both for production environments assembling multiple switches and for maintenance teams keeping replacement shaft-locking hardware available.

Typical Applications

• Compatible ABB switch-disconnector operating shafts.
• Industrial switchboard assembly.
• Electrical control-panel construction.
• Switch operating mechanism maintenance.
• Replacement of compatible shaft-locking hardware.
• OEM and panel-building applications using compatible ABB switching equipment.
