WEG’s RW Class 10 Thermal Overload Relays are designed to be used with, and as perfect compliment to WEG’s minicontactors and contactors. Effectively, RW overload relays can be mounted directly to WEG minicontactors and contactors, assuring electrical and mechanical operation as an open across-the-line starter. Features Dial FLC Setting The trip-current is set via an infi nitely adjustable dial designed with the motor’s full load current. Temperature Compensation Because RW overload relays include a fourth bimetallic strip in addition to the three that are directly heated by the motor current, ambient temperature variations in the range of -20ºC to +60ºC are no obstacle for accurate protection of your motors under even the toughest conditions. Phase Failure Sensitivity WEG overload relays include phase failure sensitivity protection as standard. This feature ensures fast tripping in case of phase loss, protecting your motor and avoiding expensive repairs / corrective maintenance services. Multi Function Button The programmable RESET button can be selected to operate in a Manual or Automatic mode, with or without TEST capabilities of the isolated trip” NC and alarm” NO auxiliary contacts. The multifunction RESET / TEST button can be set in four different positions; H (manual RESET only), HAND (manual RESET/TEST), AUTO (automatic RESET/ TEST) and A (automatic RESET only). In HAND and AUTO positions, when RESET button is pushed, both NO (97-98) and NC (95-96) contacts change states.
