That 55 kW figure at 500 V tells you the motor load it can handle under typical three-phase induction motor starting — the AC-3 rating governs the make/break of locked-rotor current, not continuous resistive load. At 690 V the same contactor derates to 25.4 kW, which is the winding stress limit at elevated voltage. Electrical life depends on duty: AC-3 maximum 850 operations per hour, AC-4 (inching/plugging) 250 per hour. For a conveyor line running one start per minute, that AC-3 rate is comfortable; for a jogging application the AC-4 limit governs and you'd need to check the actual switching frequency against 250 ops/h. Main circuit terminals are screw-type. Solid wire capacity: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), max 2x (0.75 to 4 mm²). Stranded: 2x (10 to 50 mm²). The solid/stranded range for auxiliary circuits is 2x (2.5 to 16 mm²). That 50 mm² stranded upper limit on the main terminals is generous — it takes a 1 AWG equivalent, so no adapter lug needed for heavy motor feeds up to that cross-section. That's the standard for most MCC and panel installations — no special conformal coating required for normal factory-floor humidity.","metaTitle":"Siemens 3RT1046-1AN60 SIRIUS Power Contactor, Size S3, 55 kW","metaDescription":"Siemens 3RT1046-1AN60 SIRIUS power contactor, Size S3.
