1SCA105284R1001 ABB Silver IP54 Padlockable Selector Handle

Why Choose the ABB OHSS3AH1 Selector Handle?

The ABB OHSS3AH1 is a silver selector operating handle designed for external operation of compatible ABB switch-disconnectors. Featuring clear I-O / ON-OFF indication, an IP54 protection rating and compatibility with a 6 mm operating shaft, it provides a compact operating interface for industrial switchgear and control panels.

For secure electrical isolation, the OHSS3AH1 is padlockable with one padlock using a bail diameter of 5–6.3 mm. It also incorporates door interlocking in the ON position, helping prevent normal opening of the enclosure while the associated switch remains energised.

Designed for base- and DIN-rail-mounted ABB switches, the OHSS3AH1 uses a standard 22.5 mm door drilling and is suitable for compatible OT16...125F switch-disconnectors. Its silver finish and selector-style construction provide a clean, clearly identifiable interface for industrial isolation and switching applications.

Secure External Operation and Isolation

The ABB OHSS3AH1 provides a clear external operating interface for compatible switch-disconnectors installed inside an electrical enclosure. Its selector-style design and I-O / ON-OFF markings allow the operating state to be identified directly from the panel front, while the 6 mm shaft interface transfers operation to the switch mechanism.

The ability to secure the handle with a padlock supports controlled isolation during servicing and maintenance. In addition, the ON-position door interlock helps prevent normal enclosure access while the switch remains ON, making the OHSS3AH1 well suited to industrial control panels, machinery and low-voltage distribution equipment.

Typical Applications

• ABB OT16...125F switch-disconnectors.
• Industrial switchboards and control panels.
• Machinery isolation systems.
• Low-voltage distribution equipment.
• Motor control panels.
• Enclosure-mounted industrial switching applications.
