The 170 mm depth is the key number for gland-plate clearance — make sure your enclosure has that much headroom behind the door. Side clearance of 10 mm and front clearance of 20 mm are needed for arc venting and wiring access. Main power terminals accept stranded wire from 16 to 70 mm². Auxiliary terminals handle 2x (0.5-1.5 mm²) solid or 2x (0.75-2.5 mm²) stranded, max 2x (0.75-4 mm²). That's enough for control wiring up to 4 mm² without pigtails. Lifecycle stage is marked as current — meaning Siemens still lists it as an active catalog number with no announced end-of-life. That's important for BOM freeze planning: you're not chasing a last-time buy or an NRND replacement. Auxiliary contacts are built in. Their rated switching capacity at 24 VDC is 10 A, dropping to 0.3 A at 220 VDC. That covers typical PLC and relay interface loads; for DC switching at higher voltages, check the curve against your inductive load. Coil operating range is 0.8 to 1.1 times rated value at 50/60 Hz. Pick-up and drop-out times are 40-60 ms AC or DC; arcing time is 10-15 ms. Those are standard for this frame size — no surprises on timing coordination.","metaTitle":"Siemens 3RT1054-1AF36 SIRIUS Power Contactor, 110-127 VAC Co","metaDescription":"Siemens SIRIUS 3RT1054-1AF36 power contactor, Size S6, 110-127 VAC coil, screw terminals.

The 3RT1054-1AF36 uses a screw-type coil terminal and a 110-127 VAC coil; the 3RT1055-6QF35 uses a different coil voltage and terminal style. Check your panel's coil supply and wiring preference before substituting."},{"question":"What is the depth of 3RT1054-1AF36?","answer":"The depth is 170 mm. That's the dimension from the mounting surface to the furthest projection — critical for gland-plate clearance in the enclosure."},{"question":"What wire sizes does the auxiliary terminal block accept?","answer":"Solid wire: 2x (0.5-1.5 mm²).
