Product Introduction

The ABB CHBX01L 2VAA008574R1 is positioned at the physical edge of an HN800 device row, where it provides horizontal bus extension toward the left side while also carrying the connection for 24 VDC module power. It is therefore an architectural accessory rather than a conventional analog or digital I/O module.

Its small footprint—30 mm wide, 127 mm high, and 48 mm deep—makes accurate orientation important during cabinet assembly. The matching CHBX01R 2VAA008575R1 is listed separately, so left/right orientation should never be inferred from physical appearance alone.

Core Technical Specifications

ABB CHBX01L 2VAA008574R1

ABB-associated product records identify 2VAA008574R1 as the cHBX01L Compact Bus Extender, Horizontal Left, with a 24 VDC module-power connection and the dimensions listed above.

Global Compliance & Industry Certifications

For this HN800 control-system accessory, compliance should be documented according to the applicable ABB system and installation configuration.

• CE Mark: Verify the applicable ABB conformity documentation for the equipment configuration.
• UL/cUL: Confirm whether the installed system and associated accessories are covered by the required North American certification.
• ATEX/IECEx: Do not assume hazardous-area certification for CHBX01L. Certification must explicitly cover the equipment and intended installation.
• Marine Approvals: Verify DNV or equivalent approval only where the specific configuration carries the applicable marine certification.
• WEEE: Available product data identifies the device under WEEE Category 5, Small Equipment, with no external dimension exceeding 50 cm.

The compact size does not eliminate compliance requirements. Keep the part-number record, supplier COO documentation, and applicable ABB conformity records together.

Verify specific lot certifications with OEM.

Long-Term Storage & Asset Preservation Guide

1. Keep CHBX01L in its original ESD-safe packaging. The compact bus interface is a critical mating surface; protect it from dust, oxidation, and mechanical impact while the spare remains on the shelf.
2. Maintain dry storage conditions. A relative humidity target below 60% RH is a practical warehouse-control point for electronic control accessories. Avoid condensation when transferring the unit from storage to an energized control cabinet.
3. Store left- and right-side bus extenders separately. The 2VAA008574R1 and CHBX01R 2VAA008575R1 have different connection orientations. Use clearly labeled inventory locations (this prevents a surprisingly common installation error).

Physical Installation Prerequisites

• Verify that the target installation uses the ABB Symphony Plus device-row architecture.
• Confirm that the required position is the left side of the horizontal row.
• Match / 2VAA008574R1 against the system BOM before installation.
• Confirm the 24 VDC module-power connection and associated wiring arrangement.
• Inspect the compact-bus mating surfaces before insertion.
• Do not force the extender into the adjacent device. Mechanical resistance may indicate incorrect orientation or an incompatible neighboring module.
• Maintain sufficient cabinet clearance for wiring and maintenance access; the small 30 mm body width does not define the required service clearance.
• Follow the cabinet grounding and installation requirements.
• Use ESD precautions when handling the accessory (particularly when inserting or removing it from an energized-system environment).

Buyer’s FAQ

Q: What HS tariff code should be used for ?

One supplier listing associates the product with HS 853710 and a more specific tariff number of 85371091. However, tariff classification is jurisdiction-dependent. Confirm the final code with the customs broker using the technical description “Compact Bus Extender for ABB control system” and the destination country’s tariff schedule.

Q: What Country of Origin should be declared?

Several supplier records identify Sweden as the product origin. For a commercial shipment, use the COO supported by the actual supplier/manufacturer documentation for the specific unit rather than relying solely on an online listing.

Q: Does require shipping insurance?

For a 94 g accessory, the physical freight exposure is relatively small, but insurance can still be appropriate when the part is difficult to source or has a high replacement value. Protect the compact bus interface against crushing during transport.

Q: Does contain the latest firmware?

No firmware should be assumed or separately tracked as though this were a programmable CPU. The functions as a physical compact bus extender and 24 VDC module-power connection accessory, not as a standalone controller.

Asset-control recommendation: Inventory ABB / 2VAA008574R1 as an Compact Bus Extender, Horizontal Left. Record the complete part number, orientation, COO, packaging condition, and measured shipping weight. Most importantly, keep it segregated from CHBX01R / 2VAA008575R1 because the two parts serve opposite horizontal connection directions.
