It's a current-production part — no phase-out notice on record — so it's a straight drop into a new BOM or a line-down replacement for an existing S3 footprint. Main circuit connections are screw-type terminals, accepting stranded conductors from 10 mm² up to 50 mm² (or 2x 10 AWG to 1/0 AWG). At 40 °C ambient the minimum permissible cross-section is 50 mm²; at 60 °C it drops to 35 mm² — that's the thermal derating curve in practice, so size your wire to the actual panel ambient, not the nameplate. The 53 kW at 230 V figure (at 60 °C) is the motor-switching capacity in AC-3 duty — that's the real-world number for sizing to a pump, fan, or compressor. The contactor also carries a 1 000 V rated insulation voltage, so it's comfortable in 400 V or 480 V systems with headroom to spare. That's a lot of cycles for a contactor this size — it'll outlast the machine in most conveyor or HVAC applications. RoHS compliance date is 05/01/2012, so it's fully compliant for EU and most global markets. Dimensions: 146 mm tall, 93 mm wide, 139 mm deep. The 139 mm depth is the key dimension for gland-plate clearance. Solid wire connections: accepts 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), and max 2x (0.75 to 4 mm²) for control wiring. Stranded main power wires go up to 2x (10 to 50 mm²). That's enough for a 50 mm² feed on a 53 kW motor circuit — no need for a separate terminal block.","metaTitle":"Siemens 3RT1346-1AR60 SIRIUS Power Contactor, S3, 53 kW at 2","metaDescription":"Siemens 3RT1346-1AR60 SIRIUS power contactor, size S3, rated 53 kW at 230 V 60 °C.
