Product details

SIRIUS S00 power contactor for compact motor control

The Siemens 3RT1016-1AW21 is a SIRIUS power contactor in the compact S00 frame, designed for switching motor loads in control panels up to 5.5 kW at 690 V AC. Its 24 VDC coil draws 10 A at the rated value, and the screw-type terminals accept conductors from 0.5 mm² up to 4 mm².

Ratings that define the load envelope

AC-4 at 400 V is 8.5 A, covering reversing or inching applications. For resistive loads (AC-12), the maximum operating current is 10 A. The main contact voltage rating is 480 V at both 50 Hz and 60 Hz, with an operating range of 0.8 to 1.1 times rated voltage at 50 Hz and 0.85 to 1.1 at 60 Hz.

Side-by-side mounting is allowed without derating, with a minimum 6 mm clearance to the side. Front protection is IP20; the terminal area is also IP20.

Frequently asked questions

What is the depth of the 3RT1016-1AW21?

The depth is 72 mm.

What wire sizes does the 3RT1016-1AW21 accept?

The screw terminals accept solid or stranded conductors: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), and maximum 2x (0.75 to 4 mm²). For AWG: 2x (20 to 16), 2x (18 to 14), and 1x 12.
