MNS with ACS850 integrated VSD provides a more energy-efficient and higher-performance solution.
This manual introduces the ABB MNS integrated VSD system, which combines low‑voltage switchgear with the ACS850 industrial drive. It describes the withdrawable and fixed techniques, power ratings and the benefits of a single functional unit for improved safety and energy efficiency.
The document covers engineering, procurement, project management, installation, swift commissioning, and easy maintenance. It explains how the withdrawable technique reduces mean‑time‑to‑repair, how field‑bus integration simplifies control, and provides guidance on using ABB software tools such as DriveStudio, PumpSave and FanSave.
| Withdrawable technique power rating (400 V) | 45 kW |
|---|---|
| Withdrawable technique power rating (500 V) | 55 kW |
| Fixed technique power rating (400 V) | 160 kW |
| Fixed technique power rating (500 V) | 200 kW |
| Safety standard compliance | IEC 61641, IEC 60439‑1, IEC 61489‑2, IEC 61000, IEC 60947‑4‑1 |
It is tested and verified according to IEC 61641, IEC 60439‑1, IEC 61489‑2, IEC 61000 for EMC and IEC 60947‑4‑1 for short‑circuit coordination.
The withdrawable unit can be taken out of the switchgear and replaced with a spare, reducing mean‑time‑to‑repair and keeping process availability high.
Withdrawable units are rated up to 45 kW (400 V) or 55 kW (500 V), while fixed units are rated up to 160 kW (400 V) or 200 kW (500 V).
