Rated thermal current (Ith) is 80 A, with a maximum operating voltage of 690 V. The relay is rated for 50/60 Hz operation and includes an integrated auxiliary switch that provides a dedicated \"tripped\" signal contact — a dry contact that closes when the relay has operated, useful for feeding a PLC input or annunciator panel without additional interfacing. Dimensions are 55 mm wide, 81 mm high, and 109 mm deep, fitting the S2 footprint common in Siemens motor starter assemblies. The 80 A thermal current rating at both 480 V and 600 V means this relay can carry full-load motor current up to 80 A continuously without derating across common North American voltage levels. For a 480 V motor, 80 A corresponds to roughly a 60 HP induction motor (NEC Table 430.250); at 600 V, roughly 75 HP. The Class 10E trip curve is the deciding factor for motor protection: it allows a 10-second hot-locked-rotor withstand, matching most IEC and NEMA Design B motor thermal limits. The auxiliary contact ratings cover control voltages from 24 VDC to 230 VAC: 2 A at 24 V, 4 A at 120 V, 3 A at 230 V. These are the switching capacities of the built-in signal contact — sufficient to drive a small relay coil or PLC input directly. The per-pole power dissipation is 0.07 W, negligible in a panel thermal budget. Environmental limits: operating temperature -25 to +60 °C with temperature compensation over the same range, storage and transport from -40 to +80 °C. Shock resistance is 15g / 11 ms, vibration resistance per 1-6 Hz at 15 mm amplitude and 6-500 Hz at 20 m/s² for 10 cycles. These are robust for industrial panel mounting on a machine frame or conveyor line. Substance compliance date is 10/15/2014. Wiring: the main circuit uses straight-through transformers, meaning the motor leads pass directly through the relay body — no external current transformers needed. The control terminals accept 2x 0.25 to 1.5 mm² solid or stranded wire, terminated with a Pozidriv PZ2 screwdriver tip and a 5-6 mm shaft diameter. Strip length is not stated; use standard 8-10 mm for screw terminals.","metaTitle":"Siemens 3RB3036-1WX1 SIRIUS solid-state overload relay, 80 A","metaDescription":"Siemens SIRIUS 3RB3036-1WX1 solid-state overload relay, 80 A thermal current, Class 10E trip, 690 V rated, S2 size.
