The electronic overload release provides accurate, drift-free protection compared to bimetal relays, and the integrated auxiliary switch signals the tripped state via the note 'for message \"tripped\"'. This relay mounts directly onto a contactor or as a standalone unit, using M10 bolts for the main current circuit and busbar connections. The dimensions are 120 mm wide, 119 mm high, and 155 mm deep — sized for the S10 and S12 overload relay frame. It accepts solid or stranded conductors of 2x (0.25... 1.5 mm²) for the control circuit. ## Auxiliary contact ratings and environmental withstand The integrated auxiliary switch is rated for 2 A at 24 V, 4 A at 120 V, and 3 A at 230 V, among other voltage points — these are the make/break capacities for the signaling contact that reports the tripped state. The relay withstands shock at 15g / 11 ms per IEC 60068-2-27, and vibration at 1-6 Hz with 15 mm amplitude and 6-500 Hz at 20 m/s² over 10 cycles. Storage and transport temperature range is -40 to +80 °C.","metaTitle":"Siemens 3RB2163-4GF2 SIRIUS Solid-State Overload Relay, 250","metaDescription":"Siemens SIRIUS 3RB2163-4GF2 solid-state overload relay, 250 A thermal current, adjustable trip class 5E/10E/20E/30E, 1000 V rated, for motor protection.
