1 CO contact potential free 16A/250V AC. 230V LED lamps up to 200W, incandescent lamp load 2300W. Standby loss 0.8 watt only. Modular device for DIN 60715 TH35 rail mounting. 1 module = 18mm wide, 58mm deep. With the patented Eltako Duplex technology (DX) the normally potential-free contacts can still switch in zero passage when switching 230V AC 50Hz and therefore drastically reduce wear. Simply connect the neutral conductor to the terminal (N) and L to 1(L) for this. This gives an additional standby consumption of only 0.1 watt. If the contact is used for controlling switching devices which do not perform zero passage switching themselves, (N) should not be connected because the additional closing delay otherwise causes the opposite effect. With an internal toroidal-core current transformer the single phase AC current flowing through a consumer V1 of 0.1 A up to max. 32 A is compared to the setpoint. When the latter is exceeded a relay switches off a consumer V2 connected to 2 within 0.5 seconds or switches on a consumer V3 connected to 3. Adjustment accuracy ±5%. From 25A the relay always switches on. State-of-the-art hybrid technology combines advantages of nonwearing electronic control with high capacity of special relays. The basis of current A will be set with the lower rotary switch A. The following basic values can be selected: 0.1A, 0.3A, 0.6A, 0.9A, 1.5A, 1.9A, 3.0A and 3.2A. The multiplier xA will be set with the middle rotary switch xA and offers values between 1 and 10. So currents starting from 0.1A (basis of current 0.1A and multiplier 1) can be set. OFF delay RV can be set with the upper rotary switch RV between 0 and 120 secs. The hysteresis is defined as approx. 25%. Status indication by LED. The measuring input M1-M2 is electrically isolated from power supply L-N and make contact 1(L)-2/3. Reference values larger than 32A can be adapted by an external measuring transformer.
