It comes with connecting bars for direct mounting on a 3RT106 contactor or can be installed individually. Reset is manual. This is the size S10/S12 variant, so it pairs with the larger frame contactors in that series. The 55...250 A continuous current range covers motor FLA from about 55 A up to 250 A. That puts it on 75–150 kW motors at 400 V, roughly. Class 10 means it trips within 10 seconds at 7.2× set current — standard for standard-duty induction motor starting, not for high-inertia loads that need Class 20 or 30. The electronic sensing gives better repeatability and ambient-temperature immunity than a bimetal relay. Mounting is contactor-mount on a 3RT106 contactor, using the included connecting bars that carry the motor current through the relay's CTs. The same bars let it sit standalone on a DIN rail if you prefer separate mounting. Manual reset means someone has to push the button after a trip — no auto-restart, which is the safer choice for unattended or hazardous-area machinery. No successor part to evaluate, no cross-reference to chase. If you're specifying it into a new panel, the current status holds.","metaTitle":"Siemens 3RB1065-1GG0 Electronic Overload Relay, 55-250A, Cla","metaDescription":"Siemens 3RB1065-1GG0 electronic overload relay, 55-250A, Class 10, size S10/S12.
