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.
