Product details

Siemens SIRIUS 3RT2046-3AB00 — 96 A Power Contactor, S3 Size

The Siemens SIRIUS 3RT2046-3AB00 is a power contactor in the S3 frame size, rated for 96 A at 480 V in AC-3 duty — that's the motor-switching current, so it handles a 20 hp load at 230 V and a 96 A motor at 480 V. The coil terminals are spring-type, which speeds up panel wiring compared to screw-clamp variants.

Dimensions are 140 mm high, 70 mm wide, 152 mm deep.

Wire Range and Terminals

Main power terminals accept solid wire from 2.5 to 16 mm² and stranded from 6 to 70 mm². Auxiliary contacts take 2x (0.5 to 2.5 mm²) solid or stranded. The coil connection uses spring-type terminals — no screwdriver needed for the control circuit.

Frequently asked questions

What is the 3RT2046-3AB00 rated for at 480 V?

It is rated for 96 A at 480 V in AC-3 duty, which is the motor-switching current.

Where can I buy the 3RT2046-3AB00 and get a price?

This part is sourced and quoted to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time.

What wire sizes does the 3RT2046-3AB00 accept?

Main terminals accept solid wire 2.5 to 16 mm² and stranded 6 to 70 mm²; auxiliary terminals accept 2x (0.5 to 2.5 mm²) solid or stranded.
