This Acti 9 iSSW is a linear switch used for the manual control of electric circuits. It is a 3 positions switch with 2 changeover contacts (2 C/O). The phase-separated wall can be divided to allow all the types of com busbar to pass through. It comes with staggered terminals to simplify connection. The tightening torque of connection is 1N.m for PZ1 screwdriver type. The Ue rated operational voltage is 250VAC. The Ie rated operational current is 20A. The operating frequency is 50Hz. The connection allows rigid copper cables from 0.5mm² minimum to 2×2.5mm² maximum. The connection allows flexible or with ferrule copper cables from 0.5mm2 minimum to 2×2.5mm² maximum. The number of cycles open and close (O-C) is 30000. The endurance is 30000 operations with AC22 current category under cos phi=0.8. The width in 9mm pitches is 4. The dimensions are (W) 36mm x (H) 82mm x (D) 75mm. The pollution degree is 3. The tropicalization is treatment 2 (relative humidity 95% at 55°C). The operational temperature is from -20°C to +50°C. The storage temperature is from -40°C to +70°C. It complies with IEC 60669-1 and IEC 60947-5-1 standards.
