It uses screw terminals, offers manual reset only, and comes in the S2 mounting size for direct contactor mounting. The 6...25 A adjustment range covers standard IEC motor full-load currents for small to medium induction motors — think 2.2 kW to 11 kW at 400 V three-phase. The Class 10 trip class means it will ride through a normal motor start (up to about 10 seconds of locked-rotor current) without nuisance tripping, but still protect the motor winding on a sustained overload. That makes it a solid fit for pump, fan, and conveyor drives that don't need a longer start curve. Size S2 is the physical footprint for direct mounting onto Siemens SIRIUS 3RT2 contactors in the same frame size. The screw terminals accept standard power wiring — no special tooling needed for panel integration. Manual reset only means the relay latches after a trip and requires a physical button press to re-close the NC contact in the control circuit. This is standard for applications where an automatic restart after a fault would be unsafe — conveyors, saws, presses. If your line needs automatic reset after a momentary overload, this isn't the variant. As a current-production part, the 3RB1035-1QB0 can be specified into a BOM with confidence that supply will continue.","metaTitle":"Siemens 3RB1035-1QB0 Electronic Overload Relay, 6-25A, Class","metaDescription":"Siemens 3RB1035-1QB0 electronic overload relay, 6-25A, Class 10, screw connection, manual reset, size S2.
