MNS iS is a new low-voltage switchgear from ABB. It is combined with MSpeed series to provide users with energy-saving solutions. MSpeed integrates MNS iS low-voltage switchgear and ACS850 industrial drive. The two complement each other and can bring users higher safety, higher production efficiency and lower energy consumption.
This document introduces the ABB MNS iS with M Speed solution, which combines the MNS iS low‑voltage switchgear with the ACS850 industrial drive. It highlights the safety certifications, energy‑saving benefits, and the flexibility of withdrawable and fixed techniques for motor control.
The guide also covers practical aspects such as quick‑start installation, commissioning, maintenance procedures, and the use of ABB software tools for monitoring and energy‑saving calculations.
| Withdrawable technique motor rating (400 V) | up to 45 kW |
|---|---|
| Withdrawable technique motor rating (500 V) | up to 55 kW |
| Fixed technique motor rating (400 V) | up to 160 kW |
| Fixed technique motor rating (500 V) | up to 200 kW |
| IEC safety standard | IEC 61641 (Internal Arc Safety) |
| IEC type test standards | IEC 60439‑1 and IEC 61439‑2 |
| EMC compliance | IEC 61000 |
| Short‑circuit coordination standard | IEC 60947‑4‑1 |
The withdrawable technique supports motors up to 45 kW at 400 V and up to 55 kW at 500 V.
By adjusting motor speed to match process requirements, a pump or fan running at half speed consumes only one quarter of the energy of full‑speed operation.
ABB offers the software tools “PumpSave” and “FanSave” for estimating potential energy savings.
