Torque to 0.8…1.2 N·m. The release shares the breaker's auxiliary contact slot — verify free-wheel diode polarity if the control circuit includes an inductive load.","metaTitle":"Siemens 3RV1902-1AN6 SIRIUS Undervoltage Release, 200 V","metaDescription":"Siemens SIRIUS 3RV1902-1AN6 undervoltage release, 200 V.
