Product details

Siemens 3RT6016-1AN21 — SIRIUS S00 Power Contactor

For AC-3e duty (squirrel-cage motor starting), the contactor is rated at 690 V maximum and delivers 7.5 kW at 400 V and 60 °C ambient, 13 kW at 400 V, and 22 kW at 690 V. The AC-3e maximum switching rate is 750 operations per hour, with a mechanical life of 30 million operations typical — figures that govern replacement intervals in high-cycling applications like conveyor or pump control.

The screw-type main circuit terminals accept 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm² solid or stranded conductors. Minimum permissible cross-section at 40 °C is 4 mm², at 60 °C is 2.5 mm² — important for sizing field wiring under elevated ambient conditions.

Frequently asked questions

What is the depth of 3RT6016-1AN21?

The depth is 73 mm, with a width of 45 mm and height of 57.5 mm — a compact S00 footprint.

What motor power can 3RT6016-1AN21 switch at 400 V?

At 400 V and 60 °C ambient, it is rated for 7.5 kW in AC-3e duty; at 400 V the rating is 13 kW, and at 690 V it reaches 22 kW.

Where can I buy 3RT6016-1AN21?

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

Will 3RT6016-1AN21 drop into a panel designed for 3RT6026-1AN20?

The 3RT6026-1AN20 is a larger S0 frame contactor (different footprint and terminal spacing). The S00 3RT6016-1AN21 is physically smaller — 45 mm wide vs the S0's wider body — so it will not directly interchange without adapter plates or rewiring the mounting rail.
