Product details

The 70 mm width and 140 mm height fit standard S3 panel cutouts; depth is 152 mm including terminals.

Wiring and ratings

Screw terminals accept solid conductors from 2.5 to 16 mm² and stranded from 6 to 70 mm². Fine-stranded (with ferrule) can be doubled: 2x (0.5…1.5 mm²) or 2x (0.75…2.5 mm²). Power loss at 50 Hz is 0.35 W, at 60 Hz is 0.41 W. Operating time at AC is 10 to 21 ms; arcing time is 10 to 20 ms. Auxiliary switch is included.

Switching frequency and capacity

Maximum switching rates: 900/h at AC-1 (resistive), 350/h at AC-2 (slip-ring motor), 850/h at AC-3 (squirrel-cage motor starting), 250/h at AC-4 (plugging/inching). AC-3e maximum is also 850/h. For auxiliary contacts at 24 V rated value the switching capacity is 10 A; at 48 V it is 2 A; at 60 V it is 2 A; at 110 V it is 1 A; at 125 V it is 0.9 A; at 220 V it is 0.3 A; at 230 V it is 20 hp; at 400 V it is 3 A; at 440 V it is 0.8 A.

Frequently asked questions

Where can I buy 3RT2046-1AN20 and how do I get a price?

This part is sourced to order against an RFQ through independent distribution. Submit an RFQ for current availability and pricing.

What is 3RT2046-1AN20's listed depth?

The depth is 152 mm.

What is 3RT2046-1AN20's solid conductor range?

It accepts solid conductors from 2.5 to 16 mm².

Will 3RT2046-1AN20 drop into a panel specified around 3RT2016-1AG62 without rewiring?

The 3RT2046-1AN20 is a larger S3 frame size vs the S0 frame of the 3RT2016-1AG62. Panel cutouts, DIN-rail spacing, and terminal sizes differ; direct drop-in without rewiring is not expected.

What compliance documentation does Siemens provide for 3RT2046-1AN20?

Standard Siemens SIRIUS contactor documentation applies, including RoHS and REACH declarations. The product is designed to meet relevant IEC and UL standards for industrial control equipment.
