Description
TeSys LR47 electronic overcurrent relay, 30A/690V, with automatic reset, to be supplied with 200-240V AC, for protection of motors with a rated current 3-25A. It provides 3 dials to adjust the protection, LOAD (3-30A) for the overcurrent level, O-TIME (0.3-10sec) for the acceptable duration of the overcurrent, R-TIME (1-120sec) for the automatic reset delay. 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.
