POY Finalist: Overload relays

Finalist in Electric Motors and Drives in Plant Engineering’s 2011 Product of the Year competition

By Edited by Chris Vavra, Plant Engineering November 1, 2011

The Sirius 3RB24 electronic overload relays feature IO-Link for enhanced communication. Contactors, connected to the Sirius 3RB24, provide integrated motor protection and superior communication advantages, including readout of motor current and diagnostics. Rotary switches allow for easy setting of the device’s motor current and the required trip class. A consortium made up of the leading suppliers of automation products has come together to support the new concept in all areas of sensors, actuators, and control technology. IO-Link represents an open, standardized, and manufacturer-independent system for the uniform connection of sensors and switching devices to the control level.
