The 200-540 A range covers large-frame motors typical in heavy rotating equipment; the relay mounts directly on a 3RT106 contactor or can be installed individually with connecting bars included. ## Deployment context This relay is sized for panel integration with a 3RT106 contactor or as a standalone unit. The connecting bars are included, so no extra buswork is needed for the contactor mount. Manual reset means an operator must physically clear the trip — standard for unattended or hazardous-zone machinery where automatic restart is not allowed.","metaTitle":"Siemens 3RB1065-2KG0 Electronic Overload Relay, 200-540A, Cl","metaDescription":"Siemens 3RB1065-2KG0 electronic overload relay, 200-540A, Class 20, for contactor mounting on 3RT106 or standalone.
