This Acti9 iRCP is a phase control relay. The voltage measurement range is 0.15 VAC to 10 VAC. It monitors the phases and the presence of voltage in the 3 phases of a 3-phase supply circuit. It also indicates any phase loss or reversal. It provides 1 changeover contact with fail-safe. Configuration is done with a screwdriver on the front panel with a direct scale. It could be used, for example, to control the power supply of a three-phase motor. The display accuracy is +/- 10% of the full scale. The disconnection time delay is 0.3 sec. The supply voltage Uc is 400VAC +/- 15%. The operating frequency is 50Hz or 60Hz. The output from the changeover contact current is 8A under 250 VAC with cosφ equal to 1. On the front side, the green LED indicates the presence of voltage. The red LED indicates a fault. The consumption is 3VA. The power consumption is 2W. The width in 9 mm pitches is 4. The degree of protection is IP20. The dimensions are (W) 36 mm x (H) 88.1 mm x (D) 65 mm. The operating temperature is from -5°C to +55°C. The storage temperature is from -40°C to +80°C.
