Siemens 3RT5046-1AB00 — SIRIUS S3 Power Contactor
The Siemens 3RT5046-1AB00 is a SIRIUS S3 power contactor rated for motor switching up to 66 kW at 400 V 60 °C and 114 kW at 690 V 60 °C. Screw-type terminals on both main and auxiliary circuits accept 2x (2.5 to 16 mm²) solid or stranded, or 2x (10 to 1/0) AWG.
Duty Ratings and Switching Life
The AC-3e maximum rated operational voltage is 1000 V. Mechanical endurance is 10 million cycles typical. Maximum switching rates vary by duty: 900 1/h under AC-1, 850 1/h under AC-3 or AC-3e, and 250 1/h under AC-4. The rated operating current at 50 Hz is 0.27 A for the coil. Auxiliary contact ratings: 6 A at 24 V or 230 V, 1 A at 110 V, 0.3 A at 220 V, and 3 A at 400 V. The contactor supports an auxiliary switch extension (product extension auxiliary switch: Yes).
