Purpose-Designed Cable Entry Accessory for ABB Metal Enclosed Switches

The ABB OEZXR023 ring flange cover is designed to support cable-entry arrangements in compatible ABB metal enclosed switch-disconnector systems. Industrial electrical enclosures often require carefully positioned cable entries to accommodate incoming and outgoing power or control cables. The OEZXR023 provides a cover incorporating a 22.5 mm knockout for this purpose.

Rather than functioning as a complete cable gland, the OEZXR023 forms part of the enclosure's cable-entry arrangement. The knockout is intended to be removed when an appropriately sized opening is required. The installer can then select a suitable cable-entry component according to the cable dimensions, mounting requirements and environmental conditions.

ABB lists the OEZXR023 as suitable for OEZXP_R series cable entries. This compatibility is important because ring flange covers must match the intended mounting arrangement. The OEZXR023 should not be assumed to fit every ABB enclosed switch or every flange system without checking the corresponding enclosure documentation.

The 22.5 mm dimension refers to the knockout opening diameter. It is not a statement of the overall cover diameter, the permitted cable outside diameter or a guaranteed cable gland thread size. Cable gland compatibility must be checked separately against the gland manufacturer's mounting-hole requirements and the intended sealing arrangement.

For industrial electrical installations, enclosure protection is particularly important. The final ingress protection of an assembled switch enclosure depends on the enclosure design, cover installation, sealing arrangements, cable glands and any unused openings. The OEZXR023 should therefore be installed according to the relevant ABB instructions to preserve the required protection of the complete assembly.

The OEZXR023 can be useful during new enclosure assembly, cable-entry modification and replacement maintenance. Its defined knockout size helps installers select the appropriate accessory rather than relying on improvised enclosure modifications.

As a genuine ABB accessory, the OEZXR023 also provides clear product traceability through its model number and manufacturer identification code. This is particularly useful for maintenance teams managing replacement parts across industrial switch-disconnector installations.

Understanding the 22.5mm Knockout Size

The defining characteristic of the ABB OEZXR023 is its 22.5 mm diameter knockout. A knockout is a removable section provided within an enclosure component so that an opening can be created when required.

When the knockout remains intact, the cover retains its original unopened configuration. When a cable entry is required, the knockout can be removed using an appropriate method consistent with the manufacturer's installation guidance.

After removal, the opening can be used with a suitable cable-entry fitting, provided the component is compatible with the opening size and enclosure arrangement. Any sharp edges, deformation or damage caused during knockout removal must be addressed before the installation is completed.

It is important to distinguish between knockout diameter and cable diameter. A 22.5 mm knockout does not mean that the product is designed for a cable with a 22.5 mm outside diameter. The permitted cable size depends on the cable gland or other entry fitting selected.

ABB OEZXR023 and Related Ring Flange Cover Sizes

ABB offers several ring flange covers with different knockout diameters. These variants allow installers to select the opening size required for the intended cable-entry arrangement.

• ABB OEZXR020: 20.5 mm knockout diameter.
• ABB OEZXR023: 22.5 mm knockout diameter.
• ABB OEZXR025: 25.5 mm knockout diameter.
• ABB OEZXR037: 37 mm knockout diameter.
• ABB OEZXR040: 40.5 mm knockout diameter.

These products belong to the same general ABB ring flange cover accessory family, but the knockout dimensions differ. The correct part should be selected according to the required opening and the compatibility of the complete cable-entry system.
