Overview
The ABB OHZX10 shaft alignment ring is a precision accessory engineered for disconnect switch installations where handle-to-shaft misalignment causes operational issues. Manufactured by ABB, a leader in electrical switchgear and control equipment, this alignment ring corrects fit problems and restores smooth handle operation across OT-series disconnect switches. Each unit mounts directly to the enclosure door using provided hardware, requiring no cutting or modifications to existing hardware.

Typical Applications
The ABB OHZX10 shaft alignment ring is essential in industrial control rooms, electrical substations, and manufacturing facilities where disconnect switch reliability is critical. Common applications include:
- Motor control centers (MCCs) with misaligned pistol grip handles
- Power distribution enclosures requiring smooth, reliable disconnect operation
- Legacy installations where handle-shaft fit has degraded over time
- Retrofit projects on existing OT160–OT400 disconnect switches
- Facilities requiring preventive maintenance spare parts for handle assemblies
Compatibility & Replacements
The OHZX10 alignment ring is a standard OHZ-series accessory compatible with all ABB pistol-grip external handles paired with OT-series disconnect switches. This component is particularly valuable during enclosure modifications or when handle assemblies have drifted out of alignment due to thermal cycling, vibration, or mechanical wear. Stock this alignment ring as a maintenance item to reduce downtime caused by stiff or unreliable disconnect handles. The lot of three ensures on-hand availability for multiple installations or scheduled maintenance windows.
