The Siemens SIRIUS 3RT1015-2AB01-ZX95 is a size S00 power contactor with a 24 V 50/60 Hz coil, spring-loaded terminals on both main and auxiliary circuits, and an IP20 finger-safe enclosure.
The auxiliary contact block is rated 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, and 0.3 A at 220 V — these are the make/break currents the aux contacts can handle in a control circuit, so if your PLC output drives a 24 VDC relay through this contactor's aux, the 10 A rating gives ample headroom. For motor loads, the contactor is rated 3 kW at 400 V in AC-2 duty and 6.5 A at 400 V in AC-4 duty — AC-2 covers slip-ring motor starting, AC-4 covers plugging and inching. Type 2 coordination requires a 20 A gL/gG fuse; Type 1 coordination allows a 35 A gL/gG fuse. That difference matters for selectivity studies — Type 2 leaves the contactor undamaged after a fault, Type 1 may require replacement.
Dimensions are 45 mm wide, 60 mm high, 73 mm deep — the S00 frame footprint. Spring-loaded terminals accept 2x (0.25 to 2.5 mm²) solid or stranded, or 2x (24 to 14 AWG). No screw torque to verify — spring clamp gives consistent contact force regardless of the installer's technique.
