It mounts directly onto a contactor, uses screw terminals, and is a size S2 frame. The Class 20 trip curve means it allows up to 20 seconds at 600% of the full-load current before tripping — the standard for standard-start induction motors driving pumps, fans, and conveyors where the start is not prolonged. The manual-automatic reset selector gives the commissioning engineer or MRO planner a choice: manual reset forces a local inspection after a trip (right for unattended or hazardous zones), while auto reset restarts the motor once the relay cools — useful for remote or hard-to-access installations where a nuisance trip shouldn't stop production. No broker or surplus channel is needed — the standard Siemens supply chain covers it. The screw terminals accept standard power and control wiring — no special tooling needed for panel integration.","metaTitle":"Siemens 3RB1036-2QB0 Solid-State Overload Relay, 6-25A, Clas","metaDescription":"Siemens 3RB1036-2QB0 solid-state overload relay. 6-25A, Class 20, screw connection, size S2, manual-automatic reset.
