Features
Electronic Reversing-Load Relay ELR W 3/9... electronic reversing-load relays are the practical and user-friendly further development of electronic load relays for 3-phase networks. These components feature high switching frequencies, virtually unlimited service life, no spark interference, and completely silent switching at zero voltage crossing. The compact, DIN rail-mountable modules meet all the requirements of an electronic reversing contactor circuit that has been designed specifically for industrial applications. Both the interlocking of control inputs and the complete wiring of the load contacts are incorporated in the device. Costly locking switches and contact wiring are thus a thing of the past. Cabling has been reduced to an absolute minimum. Only the following must be applied: – Control voltage, supply voltage input and output – 3-phase load The status is clearly indicated by separate LEDs for "right rotation", "left rotation", "operating voltage" or "impermissible control". A short circuit between two phases at the moment of switching is prevented by the integrated delay between the control pulse and the load control. RCV protective circuits on the output side reduce voltage peaks that occur in the load circuit to a safe level and prevent damage to the output electronics. Version With Flat-Ribbon Cable Connector and Motor Protection Relay ELR W 3/9-.../FLK/PLC-MS 9 are also equipped with a motor protection relay (MS 9). The nominal current of the MS 9 can be preselected linearly in the range from 6 A - 9 A. If the nominal current is exceeded due to overload or phase failure, the MS 9 disconnects the electronic load relay via alarm contacts. The error is indicated via an LED and also provided as a 24 V signal. In automatic mode, the ELR is automatically reactivated once the integrated bimetals have cooled down. In manual mode, a reset must be carried out manually. An integrated test function enables the thermal trigger mechanism to be simulated and thus permits the wiring to be checked before startup. 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.
