ELR 3/9-400(/SI) ELR 3/9-500 Electronic Load Relay for 3-Phase Networks Data Sheet m 01/2005 co Features Standard Version of ELR 3/9-400 and ELR 3/9-500 Electronic load relays offer the advantage of a virtually unlimited service life along with the same functions as mechanical contactors. The optocoupler technology used enables contactless, bounce-free, and wearresistant switching of loads in 3-phase networks. In comparison with conventional electromechanical components, 50 cycles per hour represents a considerable increase in cost-effectiveness. The ELR 3/9... is the fully electronic alternative to mechanical contactors. It features a compact design and low control power. A further advantage is the highquality, safe screw connection technology. nt s. Electronic Load Relay ne Version With Fuse ELR 3/9-400/SI om po Contactless switching with Triacs at zero voltage crossing does not generate any additional highfrequency disturbing pulses. This means that the ELR can be used close to modules and electronic devices with low electromagnetic compatibility (EMC). on l in ec Other key features include: – Reliable Phoenix Contact connection technology for conductor cross sections up to 6 mm2 (10 AWG) – Easy to assemble housing technology for use on EN DIN rails with a width of just 62 mm (2.441 in.) – Easy to read status indication using clearly visible LEDs All electronic load relays have a very low input power and can thus be controlled directly with any PLC or automation device. An additional RCV protective circuit for the outputs enables permanently safe operation even with inductive loads. 102147_00_en In addition to the advantages of electronic load relays already mentioned, this component also provides effective short-circuit protection. If the permissible current is exceeded, very fast fuses in the standard size of 6.3 mm x 32 mm (0.248 x 1.260 in.) disconnect the connected load. This provides optimum protection of the power semiconductor in the electronic load relay. Easily-accessible fuse holders enable fuses to be replaced quickly. In accordance with DIN VDE 0110 and DIN VDE 0636, a conductor cross section of 1.5 mm2 (16 AWG), which must be fitted with one fuse each (10 A slow-blow as mains protection), is required to connect the electronic load relay to the 3-phase network. 1 ELR 3/9-400(/SI)/ELR 3/9-500 Technical Data Input Data (Input) Control voltage Nominal current at UN Input wiring ELR 3/9-400(/SI) ELR 3/9-500 24 V DC ±20% 8 mA, approximately (typical) LED, diode for protection against polarity reversal, surge protection Output Data (Output) Operating voltage (conductor voltage) 50 Hz/60 Hz Operating voltage range Reverse voltage Maximum continuous load current Load current depending on the ambient operating temperature ELR 3/9-400(/SI) 400 V AC co m ELR 3/9-500 500 V AC nt s. 110 V AC - 440 V AC 110 V AC - 550 V AC 800 V 1200 V 3x9A Load current [A] Ambient operating temperature [°C] Figure 1 Load current depending on the ambient operating temperature on l in ec om po ne Operating time: 100% operating factor 2 102147_00_en ELR 3/9-400(/SI)/ELR 3/9-500 Output Data (Output) (Continued) Power dissipation depending on the load current ELR 3/9-400(/SI) ELR 3/9-500 m co Power dissipation [W] Operating time: 100% operating factor nt s. 1.5 4.5 7.5 Current per phase [A] Figure 2 Power dissipation depending on the load current 16 A FF – 6.3 x 32 mm (0.248 x 1.260 in.)
