SIRIUS 3RB Series — Overload Relays with Screw-type, Spring-loaded or Ring Cable Lug Connections:
SIRIUS overload relays reliably protect loads as well as other switching and protective devices in the respective load feeder against overload, phase asymmetry and phase failure. Thanks to ATEX certification, they can be used in many different applications and are even suitable for protecting motors designed for use in explosive environments. The overload relays can easily be used with the contactors of the SIRIUS module kit. Energy-efficient SIRIUS industrial controls help to minimize consumption and systematically increase efficiency. With our overload relays, you benefit from comprehensive advantages in terms of energy efficient industrial controls
For demanding applications, the modular variants of the 3RB22, 3RB23 or 3RB24 electronic overload relays even offer full motor protection using connected thermistors to sense the motor temperature, as well as comprehensive display and signaling functions, and a communication link using IO-Link. Optimized, standard accessories are available for 3RU2 and 3RB3. This helps to reduce costs for ordering and maintaining stocks. With the communication-capable SIRIUS 3RB24 electronic overload relay for IO link you can easily connect your load feeder to a higher-level control and therefore integrate it into your automation environment. As the electronic overload relay supports the transmission of analog process variables such as currents, system processes can be optimized, e.g. through load monitoring.
