WEG Overloads

RW overload relays are important equipment within the WEG Controls range of products. As usual for WEG products, extended operational service life is one of the main features you will find in RW overload relays. WEG’s RW Class 10 Thermal Overload Relays are designed to work with, and compliment WEG’s mini contactors and contactors. Effectively, RW overload relays can be mounted directly to WEG mini contactors and contactors, assuring electrical and mechanical operation as an open across-the-line starter.


Dial FLC Setting

The trip-current is set via an infinitely adjustable dial designed for 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 or 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 multi-function 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 the RESET button is pushed, both NO (97-98) and NC (95-96) contacts change states.
