Product details

SIRIUS S0 power contactor — 3RT1024-1AH10

The Siemens 3RT1024-1AH10 is a SIRIUS S0-size power contactor with three normally open main contacts and a 24 VDC coil. It mounts via screw or snap-on onto a 35 mm standard mounting rail per DIN EN 50022, fitting into standard control-panel layouts with a 45 mm width and 85 mm by 91 mm footprint. Main-circuit terminals are screw-type, accepting solid or stranded conductors up to 2x 10 mm² or 1x 8 AWG. Auxiliary contact ratings cover common control voltages: 10 A at 24 V, 6 A at 230 V, and 3 A at 400 V.

Motor-duty ratings and coordination

Rated for AC-2 duty at 400 V at 5.5 kW and AC-4 at 400 V at 12.5 A, this contactor handles reversing or inching motor loads within the S0 frame. For type 2 coordination, a gL/gG 25 A fuse is specified; type 1 coordination allows up to 63 A gL/gG.
