Product details

SIRIUS S0 power contactor — 3RT1024-1AC10

The Siemens SIRIUS 3RT1024-1AC10 is an S0-frame power contactor with three normally-open main contacts, screw-type terminals, and a 24 V 60 Hz coil. It mounts via screw or snap-on onto a 35 mm DIN rail per DIN EN 50022, fitting into a standard panel cutout at 45 mm wide × 85 mm tall × 91 mm deep.

Motor duty and switching ratings

For AC-4 inching and plugging, it's rated 12.5 A at 400 V. Auxiliary contact capacity is 10 A at 24 V, 6 A at 230 V, and 0.3 A at 220 V DC.

Coordination and wiring

Type 2 coordination requires a 25 A gL/gG fuse; Type 1 allows up to 63 A. Main circuit wiring accepts 2x (1 to 2.5 mm²) or up to 2x 10 mm² solid/stranded.

Frequently asked questions

Will 3RT1024-1AC10 drop into a panel specified around 3RT1023-1AL20 without rewiring?

The S0 frame dimensions and DIN rail mounting are identical, so the mechanical fit is the same. However, the coil voltage differs — verify your control circuit voltage matches the 24 V 60 Hz coil before installing.
