Phase control ➜ EWS2 ■ Space savings, accurate measurement and optimized functions all improve the efficiency of your electrical installation ■ Control : You simply install your EWS2 phase control relay and without any adjustment you can monitor the loss or inversion of one of the phases ■ Safety : The EWS2 range enables you to choose the level of safety for your installation by using versions with 1, 2 or 3 output changeovers ■ Self-powered : Simple to install, EWS2 control relays use the controlled mains supply for their own power supply voltage Part numbers Type EWS2 Output relay 2 changeovers Code 84 873 034 General characteristics Input Operating range Operating range Frequency Maximum consumption Output Output relay Type of contacts Nominal rating Maximum breaking voltage Nominal breaking capacity Min. breaking current Electrical life (number of operations) Maximum rate (at full load) Mechanical life (operations) Pick-up delay T1 Turn-off delay T2 Connection capacity - without ferrule Connection capacity - with ferrule Max. tightening torque (IEC/EN 60947-1) Environment Operating temperature range (oC) Storage temperature (0C) Housing material Protection (IEC/EN 60529) - Casing Protection (IEC/EN 60529) - Term. block Dielectric strength (IEC/EN 60255-5) Insulation coordination (IEC/EN 60664-1) Weight (g) 1 3 x 230 ➞ 3 x 400 V a 3 x 200 ➞ 3 x 484 V a 50 / 60 Hz 28 VA 2 changeovers No cadmium 8A 250 V a 2 000 VA 10 mA / 5 V c 105 at 8A/250 V a 360 operations / hour 10 x 106 ≤ 650 ms < 300 ms 1 x 0.5 ➞ 4 mm2 (AWG 20 ➞ AWG 11) 2 x 0.5 ➞ 2.5 mm2 (AWG 20 ➞ AWG 14) 1 x 0.5 ➞ 2.5 mm2 (AWG 20 ➞ AWG 14) 2 x 0.5 ➞ 1.5 mm2 (AWG 20 ➞ AWG 16) 0.6 ➞ 1 Nm / 5.3 ➞ 8.8 lbf.in -20 ➞ +50 -40 ➞ +70 Self-extinguishing IP40 IP20 2.5 KV / 1 mn / 1 mA / 50 Hz Overvoltage category III, degree of pollution 3 : 4 KV / 3 86 Dimensions (mm) EWS / EWS2 68 44 22.5 2.6 90 67.5 45 23.2 5.5 Connections EWS2 L1 L2 L3 L1 L2 11 L3 21 R 3 12 R 14 22 24 Principles Timing diagrams EWS2 Td : Power on delay Tr : Responsable time after a fault has occurred R : Output relay 100% L1 0% 100% L2 0% L3 100% L3 0% L2 Tr R Tr Tr Tr On Off Td Td Td Td 2 Mouser Electronics Authorized Distributor Click to View Pricing, Inventory, Delivery & Lifecycle Information: Crouzet: 84873034
