This Acti9 CDS is single-phase load-shedder for 1 pole installation with 1 relay per phase. When the consumption exceeds the selected threshold, it temporarily cuts off the power supply to non-priority circuits. It increases the number of loads without modifying the installed power. The load-shedding and restoration in cascading configuration of 2 non-priority circuits via 2 relays with time-delayed action. This device reduces the installed power and prevents nuisance tripping of the upstream circuit breaker. The Iu Rated current is 5A to 90A. The Rated current (control contacts) is 1A. The Ui insulation voltage is 230VAC. The Ue operating voltage is 230VAC +/- 10%. The operating frequency is 50Hz or 60Hz. The power consumption is 12VA. The active power is 20kW maximum. The connection is done with rigid coper cables 10mm² to 50mm² or flexible or with ferrule copper cables 10mm² to 35mm². The dimensions are (W) 90mm x (H) 77mm x (D) 60mm. The width in 9mm pitches is 10. The weight is 300g. The degree of protection is IP20 and IP40 for a device in modular enclosure. The Operating temperature is -5°C to +50°C. The Storage temperature is -40°C to +70°C. It complies with NF C 61.750 and EN 500.81.1 standards.
