Product introduction

The ABB D30A2893 (4910330630) is a genuine OEM service and refurbishment kit engineered for ABB’s 4-pole contactor assemblies. This precision-manufactured kit combines critical replacement elements — including the electromagnetic coil, control electronics, damping elements, terminal protection cover, and mounting fasteners — into a single, ready-to-install package. It is specifically intended to restore the electrical and mechanical integrity of medium- and high-power contactors used in heavy-duty industrial control systems.

As part of ABB’s comprehensive service portfolio, the D30A2893 (4910330630) ensures continuity and consistency in existing installations by maintaining identical form, fit, and function with the original contactor components. Designed for integration into ABB AF-series and ZAF-series four-pole contactors, the kit delivers the same performance and safety ratings as the factory-assembled unit. Its function is to simplify maintenance and reduce total downtime by providing a complete, factory-matched solution for rapid replacement of worn or failed internal parts.

In modern automation and power-distribution systems, reliability and uptime are critical. The ABB D30A2893 (4910330630) supports this requirement by extending the operational lifespan of existing contactors, restoring their original switching accuracy, thermal performance, and safety compliance. It is a practical and cost-efficient component for sustaining long-term productivity in industrial plants.

Typical application scenarios

The ABB D30A2893 (4910330630) is primarily used in industrial and commercial electrical systems that rely on heavy-duty contactors for load control. It is suitable for environments such as manufacturing lines, chemical plants, mining operations, steel mills, and process industries where AF580 to AF1250 contactors are widely deployed. These contactors typically control large motors, compressors, or heating elements operating under continuous duty cycles.

In motor control centers (MCCs), the ABB D30A2893 (4910330630) is used during preventive maintenance or equipment refurbishment to replace damaged coils or control modules that may have degraded due to heat, voltage transients, or mechanical stress. The kit ensures that the refurbished contactor maintains its electrical endurance, coil response, and arc suppression characteristics.

For retrofit projects, it allows engineers to maintain consistent ABB technology across older and newer panels, ensuring uniform system performance. Its modular, field-serviceable design makes it ideal for large facilities that prioritize minimizing production downtime and standardizing spare parts inventory.
