Compact Switches

The term „Compact Switch“ is common practice in the industry and describes a design of disconnect switches. It is about On-Off switches arranged for switchboard installation. In the majority of cases the switches are drafted for snap-on DIN rail mounting, base mounting or front mounting in the door. The terminal screws are all accessible from one side and are situated in line of the conduct. The Compact Switches are classified in 3 groups starting with the basic series ML0 with applications from 25A to 32A. The well proven series ML1 to ML3 from 16A up to 125A and the high-performance series ML4- ML7 from 125A to 630A. The technical details of these series are listed in the following pages.
