Siemens Protecting with 3RB22/3RB23
Our modular solid-state 3RB22/3RB23 overload relays – that provide full motor protection – offer the highest level of functionality and protection. These devices not only protect your loads as a function of the current, but also as a function of the temperature because a PTC thermistor
sensor is connected. The PTC sensor directly measures the temperature of the motor windings which is then evaluated by the relay.
The advantages at a glance
 Variants reduction due to setting range of 1:10 Full motor protection by a connected PTC-sensor Transmitting operating data/communication via analog output
Our SIMOCODE pro motor management system is the optimum choice if you wish - in addition to the features of the 3RB22/3RB23 relays - to have even more extensive control functions. These include user-friendly diagnostic capabilities and high-performance communications with PROFIBUS DP.
