The screw connection terminals match standard panel wiring practice, and the relay is configured for manual reset only — no auto-reset option on this variant. Size S2 footprint keeps the assembly compact on the DIN rail. The 6…25 A adjustment range covers motor FLA from fractional-horsepower up to roughly 7.5 kW at 400 V three-phase, depending on service factor. Class 20 means the relay allows up to 20 seconds of locked-rotor current before tripping — standard for general-purpose induction motors driving pumps, fans, and conveyors where start-up is not prolonged. Manual reset keeps the circuit locked out after a trip, which is the typical requirement for unattended or safety-monitored lines.","metaTitle":"Siemens 3RB1035-2QB0 Electronic Overload Relay, 6…25 A, Clas","metaDescription":"Siemens 3RB1035-2QB0 electronic overload relay, 6…25 A, Class 20, screw connection, manual reset, size S2.
