...connects or disconnects automatically another load with a potential-free contact upon starting a machine, lamp etc. The module is simply looped in a lead of the electric mains of the machine. Consequently, it is not necessary to intervene in the machine. Suitable for consumers of 230 V alternating voltage or 410 V three-phase current. For consumers 250 - 4000 W. The switching contact (1 x switch over) may be loaded with max. 10 A. Use: Automatic connection of a vacuum cleaner when switching on a machine, automatic safety-cutoff when starting another machine, delayed (approx. 0.5 sec.) automatic connection of a second machine if the house fuse blows in case of simultaneous connection.
