For AC-4 reversing or plugging duty, the rating drops to 11.4 kW at 690 V, which reflects the higher electrical wear from switching under load. The coil is wound for 230 V at both 50 Hz and 60 Hz, with an operating range of 0.8 to 1.1 times rated voltage at 50 Hz and 0.85 to 1.1 at 60 Hz. That means it picks up cleanly even if the line sags to about 184 V, and holds in through brownout conditions down to about 195 V. The 55 mm width and 112 mm height fit a standard 8-module enclosure row. The auxiliary circuit terminals handle 2x solid 0.5 to 1.5 mm² or 2x stranded 0.75 to 2.5 mm². That covers most panel wiring from 1.5 mm² control cable up to 16 mm² motor feeders. ## Environmental and protection The front face carries IP20 — finger-safe for the control voltage terminals. The terminal area itself is IP00, meaning the power connections are exposed and need enclosure protection.","metaTitle":"Siemens 3RT1036-1AL20-ZW96 SIRIUS Power Contactor, S2, 30 kW","metaDescription":"Siemens SIRIUS 3RT1036-1AL20-ZW96 power contactor, size S2, 30 kW at 400 V AC-3, 230 V 50 Hz / 230 V 60 Hz coil.
