DSE1 LASTABWURFRELAIS

This Acti 9 DSE1 is a load shedding device to temporarily cut off the power supply to non-priority circuits and reduce the installed power. This single-phase load shedding is used to increase the number of loads without modifying the installed power and to do the restoration of 1 non-priority channel. It prevents nuisance tripping of the upstream circuit breaker for 1P installation. The load-shedding indication is made by a red indicator and by buzzer. The tripping threshold is adjustable from 0.8kW to 7kW (by default 3.7kW). The power consumption is 5VA backlit, 3.5VA not backlit. The pre-alarm time before load-shedding (Ton) is adjustable from 0s to 9999s (by default 60s). The load-shedding time (Toff) is adjustable from 0s to 9999s (by default 120s). The buzzer operating time (Tbe) is adjustable from 1s to 9999s (by default 60s). The Backlit LCD displays 3 digits after the decimal point. The connection allows rigid copper cables of 6mm² and flexible or with ferrule copper cables of 6mm² The tightening torque of connection is 1.2N.m for PZ2 screwdriver type. The Ue rated operational voltage is 230VAC -15% +10%. The Ui rated insulation voltage is 230VAC. The frequency is 50Hz or 60Hz. The threshold is from 3.5A to 32A, accuracy -/+1%. The rating priority circuit is 32A with cos phi equal to 1. The active power is 40W to 8kW, 32A maximum. The degree of protection is IP20 at terminals and IP40 device in modular enclosure. The tropicalization is treatment 2 (relative humidity 95% at 55°C). The width in 9mm pitches is 4. The dimensions are (W) 36mm x (H) 87mm x (D) 60mm. The weight is 130g. The mounting position of installation is indifferent from 0° to 360°. The operational temperature is from -5°C to +50°C. The storage temperature is from -40°C to +70°C. It complies with IEC 64-8 standard.
