Our Ranges

From 0.1 to 100 A , the MMS range combine motor control and protection in a single unit which can be equipped with many other accessories. Major applications for MMS's are small machine tools, pumps, compressors, etc.

MS 116 cover the lower ranges up to 7.5kW / 16A and provide cost effective and economic motor protection in many applications.Very efficient is the small width, thanks to which the customers can save space and costs in installations. 

MS 325 is a high performance Manual Motor Starter up to 12,5kW / 25A at 400V with a high short circuit capacity up to 100KA with a very low "energy let through"-value.

MS 450 and MS 495 are for the protection of bigger motors up to 45 kW / 100A.

All Manual Motor Starters can switch, disconnect and protect motor against :

short circuit

thermal overload

phase failure
