1SCA105271R1001 ABB Grey Selector Handle IP54 Padlockable with ON-Position Door Interlock

Why Choose the ABB OHGS3AH1 Grey Selector Handle?

The ABB OHGS3AH1 is a compact and reliable grey selector operating handle designed for external operation of compatible ABB switch-disconnectors. Designed for base-mounted and DIN rail-mounted switching equipment, it provides clear manual ON/OFF operation through an electrical panel or enclosure door.

The OHGS3AH1 has an IP54 protection rating and is designed for a 6 mm operating shaft with 22.5 mm door drilling. Clear I-O and ON-OFF indication makes switch position easy to identify, while its selector-style construction provides a compact operating interface for industrial and commercial low-voltage installations.

For controlled isolation, the OHGS3AH1 is padlockable with one padlock with a 5–6.3 mm bail diameter and incorporates a door interlock in the ON position. It is suitable for compatible ABB OT16–OT125F switch-disconnectors, providing secure external operation for switchboards, control panels and electrical enclosures.

Key Advantages

• Compact grey selector handle for ABB switch-disconnectors.
• IP54 protection rating for panel and enclosure applications.
• Padlockable with one padlock to support secure electrical isolation.

Secure External Control for ABB Switch-Disconnectors

Selector handles provide an external operating interface for switch-disconnectors installed within electrical panels and enclosures. The ABB OHGS3AH1 operates compatible equipment through a 6 mm shaft, allowing the switching mechanism to remain inside the enclosure while providing clear ON and OFF control from the panel exterior.

The OHGS3AH1 additionally incorporates door interlocking in the ON position, meaning the enclosure door cannot normally be opened while the handle is in the ON position. Combined with IP54 protection and padlocking capability, this makes the handle particularly suitable for industrial switching and isolation applications requiring controlled access to enclosed electrical equipment.

Typical Applications

• ABB OT16–OT125F switch-disconnector installations.
• Industrial low-voltage distribution switchboards.
• Electrical control panels and cabinets.
• Machinery isolation and switching systems.
• Base-mounted and DIN rail-mounted switch installations.
• Enclosures requiring ON-position door interlocking.
