It mounts directly on a 3TF68 or 3TF69 contactor or can be installed individually, with a manual reset. ## Integration notes The connecting bars are included, so no separate busbar kit is needed when mounting to the 3TF68/69 contactor. The S10/S12 frame size matches the contactor interface. Manual reset means the relay stays tripped until someone presses the reset button — a deliberate choice for applications where automatic restart after a fault is not acceptable.","metaTitle":"Siemens 3RB1065-1LG0 Electronic Overload Relay, 300-630A, Cl","metaDescription":"Siemens 3RB1065-1LG0 electronic overload relay, rated 300-630A, Class 10, for 3TF68/69 contactors.
