The size S3 frame mounts directly to a SIRIUS contactor or as a standalone unit on the DIN rail. Manual or automatic reset is selectable on the front — useful for remote or unattended restart scenarios. The 25...100 A adjustment window means this relay covers a wide band of motor full-load currents — from a 25 A motor up to a 100 A motor — without changing the unit. Class 20 means it tolerates up to 20 seconds of locked-rotor current before tripping, matching standard IEC motor starting profiles for pumps, fans, and conveyors. The S3 frame size determines the physical footprint and the contactor it mates with: it sits on the same rail as the SIRIUS 3RT2 contactors in the S3 frame.","metaTitle":"Siemens 3RB1046-2EB0 Solid-State Overload Relay, 25-100A, Cl","metaDescription":"Siemens 3RB1046-2EB0 solid-state overload relay, 25-100A, class 20, size S3, manual-automatic reset.
