Mounting is via screw fixing with a vertical mounting surface that can be rotated ±90° or tilted ±22.5° front-to-back — useful when fitting into tight or odd-angled panel layouts. The contactor dimensions are 170 mm deep, 120 mm wide, and 172 mm high, so plan your enclosure depth accordingly. Power cable termination accepts stranded conductors from 25 mm² up to 120 mm² — big enough for the main feed on a 100 A+ motor circuit. The coil uses screw-type terminals with a solid/stranded range of 0.5–1.5 mm² (two conductors) or 0.75–2.5 mm² (two conductors), max 4 mm². Auxiliary switch is present, which simplifies adding status feedback or interlocking without a separate block. The contactor also carries a mechanical life of 10 million operations typical, so it will outlast most panel refreshes. ## Switching performance The coil draws 10 A at 24 V rated value and derates at higher voltages: 2 A at 48 V, 2 A at 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, and 3 A at 400 V.","metaTitle":"Siemens SIRIUS 3RT1054-6LA06 Power Contactor, S6 Size, 170 m","metaDescription":"Siemens SIRIUS power contactor 3RT1054-6LA06, size S6, screw-type coil terminals, 170x120x172 mm, 25–120 mm² stranded, 1000 ops/h AC-3.
