The coil is rated for 48 V at both 50 Hz and 60 Hz, with an operating range factor of 0.8 to 1.1 at 50 Hz and 0.85 to 1.1 at 60 Hz. ## Terminals, wiring, and environmental limits Main current circuit connections use screw-type terminals. Solid wire capacity is 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), and max 2x (0.75 to 4 mm²). The contactor enclosure front is rated IP20, while the terminal area is IP00 — meaning the terminals are unprotected against touch or debris ingress once wired, so panel builders must account for this in the enclosure design. Dimensions are 112 mm height, 73 mm width, and 115 mm depth. Operating times: AC closing 10 to 30 ms, arcing time 10 to 15 ms. ## Auxiliary contact ratings and compliance Auxiliary contacts are rated for switching at various voltages: 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, 0.3 A at 220 V, 6 A at 230 V, and 3 A at 400 V. These ratings cover typical control-circuit loads such as PLC inputs, relay coils, and indicator lamps.","metaTitle":"Siemens 3RT1336-1AH20 SIRIUS Power Contactor, 23 kW at 230 V","metaDescription":"Siemens SIRIUS 3RT1336-1AH20 power contactor, size S2. 23 kW at 230 V 60°C, 11 kW AC-2 at 400 V. 690 V insulation.
