Screw connection means no crimp tool needed for the field swap — strip, insert, torque. The coil draws from the 24 V DC bus; confirm the supply can deliver the inrush current without dropping below the pick-up voltage. If your panel uses a different coil voltage or terminal type, the 3RT5934 family covers other variants.","metaTitle":"Siemens 3RT5934-5BB41 SIRIUS magnet coil, 24 V DC, size S2","metaDescription":"Siemens 3RT5934-5BB41 SIRIUS magnet coil for contactor size S2, 24 V DC screw connection.
