| Long Description | TeSys LR47 electronic overcurrent relay, 60A/690V, with manual reset, to be supplied with 24V AC/DC, for protection of motors with a rated current 5-50A. It provides 3 dials to adjust the protection, LOAD (5-60A) for the overcurrent level, O-TIME (0.3-10sec) for the acceptable duration of the overcurrent, D-TIME (0.5-30sec) for the starting duration. In addition, the device trips when there is a missing phase during more than O-TIME. The device has a reset button, a test/stop button, 2 LED indicators (Run/Trip), 2 auxiliary contacts 1NO+1NC for fault signalling. Settings can be locked by sealing the transparent cover. DIN rail mounting, without power terminals (currents monitored by 2 current transformers crossed by the motor cables). Multi standards certified (IEC, UL, CSA, CCC, EAC), it conforms to RoHS/REACh regulation. | Directly mountable on the LSIS Metasol MC. Real time processing and high precision by Micro controller unit. EMPR has high performance under the harmonic noise and can be used in the Inverter control circuit (20~200Hz). Multiple protection and Wide current setting range. Overcurrent, Phase loss, Locked rotor, Phase unbalance and Phase reversed. Standard: IEC60947-1, IEC60947-4-1, IEC60947-5-1, UL508, KSC4504. Certification & approval: CE, UL, Korean Safety, CCC. |
