| ESIS
Series Installation contactors |
The contactor types ESIS 20, ESIS 24, ESIS 40 and ESIS 63 are driven by DC solenoid systems characterized by hum free continuous operation and an almost imperceptible switching sound. They are energized by AC voltage flowing via integral diodes. The contactors ESIS 21 are drive by AC solenoid systems. The contactors additionally include a suppressor circuit against overvoltages and to limit interference spikes in the solenoid system. All types include 2 to 4 equally rated NO/NC contacts which can be used as main or auxiliary poles. |
