It protects motor circuits by monitoring current and tripping on overload — the integral auxiliary switch carries a note for message 'tripped'. Trip class is field-adjustable across CLASS 5E, 10E, 20E and 30E, so you match the relay to the motor's thermal withstand curve without stocking multiple variants — a single part covers fast-acting (5E) through slow-blow (30E) profiles. AC-3e switching is also rated to 690 V maximum. The overload relay uses straight-through transformers for the main current circuit, meaning the power conductors pass directly through the relay body — no separate CTs to wire. Stand-alone installation and any mounting position simplify panel layout. Auxiliary contact ratings span control voltages: 2 A at 24 V, 4 A at 120 V, 3 A at 230 V, and 0.11 A at 220 V (–). The integrated auxiliary switch saves panel space over a separate contactor block. ## Deployment context Vibration resistance to 1–6 Hz, 15 mm; 6–500 Hz, 20 m/s²; 10 cycles, and shock resistance 15g / 11 ms — it holds up on conveyor lines and pump skids. The substance prohibitance date of 10/15/2014 indicates RoHS/REACH compliance documentation is on file — useful for quality doc control and PO trace. No official successor has been issued — this remains the current offering in the SIRIUS S2 solid-state overload relay line.","metaTitle":"Siemens 3RB3133-4WX1 SIRIUS Solid-State Overload Relay, 80 A","metaDescription":"Siemens 3RB3133-4WX1 SIRIUS solid-state overload relay, size S2, 80 A thermal current, adjustable trip classes 5E–30E, 690 V rated voltage.
