Product details

Product Introduction

Siemens SIRIUS power contactor 3RT2024-1AF00 is a 3-pole size S0 contactor with a 110 V AC coil and screw terminals. It includes a factory-fitted auxiliary contact block (1 NO + 1 NC) and is rated for AC-3 motor starting duty. Typical applications include control cabinet retrofits, motor control centers, and spare replacement for aging S0-size contactors in industrial panels.

Panel cutout planning: the contactor measures 97 mm depth, 45 mm width, and 85 mm height. It snaps onto a 35 mm DIN rail per EN 60715 and can be rotated ±180° on a vertical surface or tilted ±22.5° forward/backward. Minimum clearances: 10 mm upward, forward, and downward; 6 mm to the side. Derating may apply if these gaps are reduced.

The auxiliary contact terminals handle 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) solid or stranded. Screw-type connections; ferrules recommended for fine-stranded wire but not mandatory within the listed range.

Environmental Ratings

Suitable for indoor control cabinets without condensation.

Frequently asked questions

What are the exact mounting dimensions for the 3RT2024-1AF00?

Depth 97 mm, width 45 mm, height 85 mm. Clearances: 10 mm up, down, and forward; 6 mm to the side. Mounts on 35 mm DIN rail per EN 60715 with ±180° rotation on vertical surfaces.

What is the mechanical life at 1000 operations per hour for AC-3 duty?

Mechanical life is typically 10 million operations. At AC-3 the contactor is rated for up to 1000 switching cycles per hour.

What wire sizes can the terminals accept?

Main terminals: solid or stranded 1 to 10 mm². Auxiliary terminals: 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) solid/stranded. Screw-type terminals.
