The S3 frame size (70 mm wide, 146 mm tall, 139 mm deep) fits standard 35 mm and 75 mm DIN rail via screw and snap-on mounting, with side-by-side mounting permitted for multi-contactor assemblies. The contactor's switching frequency depends on the duty category. At AC-1 it manages up to 900 operations per hour; at AC-3 the maximum is 850 operations per hour. ## Power ratings and thermal derating Motor power ratings are given at 60 °C ambient: 38 kW at 230 V, 66 kW at 400 V, and 114 kW at 690 V. The 690 V rating of 25.4 kW at 50 Hz (likely a different duty or temperature basis) shows the derating curve matters — always size against the 60 °C column for panels with elevated internal temperatures. Conductor sizing follows: at 40 °C the minimum permissible cross-section is 50 mm²; at 60 °C it rises to 35 mm² (solid/stranded 2x 2.5…16 mm² per terminal, or AWG 2x 10…1/0). ## Control circuit and auxiliary contacts The control coil draws 6 A at 24 V, 6 A at 230 V, 3 A at 400 V, 1 A at 110 V, and 0.3 A at 220 V (all 50 Hz). The product extension for auxiliary switches is available, and both main and auxiliary/control circuits use screw-type terminals — no spring-cage option on this variant. For the main current circuit, screw terminals accept 2x (2.5…16 mm²) solid/stranded or 2x (10…1/0) AWG.","metaTitle":"Siemens 3RT5046-1AF00 SIRIUS Power Contactor, S3, 70 mm","metaDescription":"Siemens SIRIUS power contactor 3RT5046-1AF00, S3 frame, 70 mm width, 139 mm depth, 1000 V insulation voltage, AC-3e rated 1000 V max.
