SIRIUS 3RT1015-1AH01-ZW95 — Power Contactor, Size S00, 24 VDC Coil
The Siemens SIRIUS 3RT1015-1AH01-ZW95 is a power contactor in size S00, designed for switching motor loads and resistive circuits in industrial control panels. It mounts on a 35 mm DIN rail per DIN EN 50022 and uses screw-type terminals for the main circuit. The 24 VDC coil draws its rated current at the listed operating range of 0.8 to 1.1 times the rated voltage at 50 Hz and 0.85 to 1.1 at 60 Hz — ensure the control supply stays within these bounds for reliable pick-up and drop-out. Rated for AC-12 duty at 10 A maximum, this contactor handles resistive loads up to that current. For motor duty, the AC-2 rating at 400 V is 3 kW, and the AC-4 rating at 400 V is 6.5 A — the AC-4 figure governs reversing or inching applications where the contacts break the motor at full current.
DIN Rail Integration and Wiring
Snap-on mounting onto a 35 mm standard mounting rail per DIN EN 50022. Side-by-side mounting is permitted, with a minimum side clearance of 6 mm to adjacent devices for heat dissipation. Main circuit terminals accept solid or stranded conductors: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or max. 2x (0.75 to 4 mm²). AWG equivalents are 2x (20 to 16), 2x (18 to 14), and 1x 12. Front and terminal protection is IP20. Dimensions: 45 mm wide, 57.5 mm high, 72 mm deep — fits standard S00 footprint. Operating temperature range is -25 to +60 °C, with a maximum operating altitude of 2000 m. Pollution degree 3 for industrial environments.
Lifecycle and Sourcing
Mechanical life is 30 million operations typical. For type 1 coordination, the required fuse is gL/gG 35 A; for type 2 coordination, it is gL/gG 20 A.
