Abstract (en)
[origin: EP1503395A2] In energizing, one contactor (1) contains electronic energizing control (AS) with two high current inputs (A1,2) for pulsewidth modulated DC energizing of magnetic drives (K1,2) of all contactors (1,2), in specified, resistance containing connection. Low current control inputs (A10,11) are bridged by thermo-switches (TS1,2), breaking on attaining preset limit temperature,each allocated to one contactor and thermally coupled to inner current rails (S13,21), leading to main contacts (HA1,2) of each contactor.
