The operating frequency is 50-60 Hz, matching standard line frequencies worldwide. Stand-alone installation means it mounts independently, not ganged to a contactor — useful for retrofit or when the contactor is already in place. The auxiliary switch is integrated and provides a \"tripped\" message signal (Note: for message \"tripped\"). Contact ratings: 2 A at 24 V, 4 A at 120 V, 3 A at 230 V — sufficient to drive a PLC input or indicator lamp in the control circuit. Shock resistance is 8g / 11 ms for the signaling contact in tripped position, and 15g / 11 ms per IEC 60068-2-27 for the main body. Vibration resistance covers 1-6 Hz at 15 mm amplitude and 6-500 Hz at 20 m/s² for 10 cycles — suitable for mounting on machinery or in panels subject to moderate vibration. This relay is sized for the S3 frame, with dimensions 70 mm wide × 106 mm high × 124 mm deep. It uses straight-through transformers for the main current circuit — the power conductors pass through the relay without looping — which simplifies wiring in a panel. Mounting position is any, giving flexibility in crowded enclosures. Wire termination accepts 2× (0.25 to 1.5 mm²) solid or stranded, with a Pozidriv PZ 2 screwdriver tip (shaft diameter 5-6 mm).","metaTitle":"Siemens 3RB3046-1XX1 SIRIUS solid-state overload relay, S3,","metaDescription":"Siemens 3RB3046-1XX1 SIRIUS solid-state overload relay, size S3, rated thermal current 115 A, Trip Class 10E, 50-60 Hz.
