Description
Schneider Electric LT4760M7S TeSys LT47 Electronic Overcurrent Rly 5-60A 240Vac
TeSys LR47 electronic overcurrent relay, 60A/690V, with manual reset, to be supplied with 200-240V AC, 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.
