The main circuit uses screw-type terminals accepting 1x 50 mm² or 2x 10–35 mm² stranded, so it lands on typical motor-circuit conductors without adapters. The CLASS 20E trip class is standard for general-purpose motor starting. Auxiliary contact ratings cover both 24 VDC (2 A) and 120 VAC (4 A) signal circuits, so it interfaces cleanly with PLC inputs or contactor coils. The integrated auxiliary switch is NC/NO, with the note \"for message 'tripped'\" — meaning the signaling contact changes state only on a trip event, not on power loss. Fastening method is contactor mounting — it clips directly onto the matching SIRIUS contactor, saving DIN rail space and eliminating interconnecting wiring between the overload and the contactor. Dimensions are 55 mm wide × 99 mm high × 104 mm deep, so it fits the S2 frame footprint. Vibration resistance tested to 1–6 Hz at 15 mm amplitude and 6–500 Hz at 20 m/s² for 10 cycles; shock resistance 15g for 11 ms. That's robust enough for machine-mounted applications near vibrating equipment.","metaTitle":"Siemens SIRIUS 3RB3036-2WB0 Solid-State Overload Relay, CLAS","metaDescription":"Siemens SIRIUS 3RB3036-2WB0 solid-state overload relay, CLASS 20E, 60 A thermal current, 690 V rated.
