It is designed for motor protection in three-phase AC circuits operating at 50 to 60 Hz, with a trip class of CLASS 20E — meaning it will trip within 20 seconds at 7.2× the current setting, per IEC 60947-4-1. The 80 A thermal current (Ith) at both 480 V and 600 V tells you the relay can carry that current continuously through the main circuit — it is the continuous rating, not the motor FLA. The auxiliary switch is integrated and rated for 2 A at 24 V, 4 A at 120 V, and 3 A at 230 V — these are the contact ratings for the trip/alarm signal; verify the load in your control circuit does not exceed these values. The CLASS 20E trip class is the standard for general-purpose motor starting (conveyors, pumps, fans); it allows the motor to draw starting current for up to 20 seconds without nuisance tripping. The main current circuit uses straight-through transformers, so the power conductors pass through the relay without looping. Wire sizes: solid or stranded, 1x (0.5 to 4 mm²) or 2x (0.5 to 2.5 mm²) per terminal. The screwdriver tip required is Pozidriv PZ 2, shaft diameter 5 to 6 mm. Dimensions: 55 mm wide, 81 mm high, 109 mm deep — fits the S2 footprint common in Siemens SIRIUS panels. Vibration resistance: 1 to 6 Hz at 15 mm amplitude, 6 to 500 Hz at 20 m/s², 10 cycles per axis. Shock resistance: 15g for 11 ms on the main relay; the signaling contact (97/98) in the tripped position is rated for 8g / 11 ms per IEC 60068-2-27. This makes it suitable for installation in cabinets on factory floors with moderate vibration, not for direct machine-mount without isolation.","metaTitle":"Siemens 3RB3036-2WW1 SIRIUS Solid-State Overload Relay, CLAS","metaDescription":"Siemens 3RB3036-2WW1 SIRIUS solid-state overload relay, CLASS 20E, 80 A thermal current, 690 V rated, 109 mm depth.
