The official successor is the SIRIUS 3RT2 series. The AC-3 rating of 9 A at 400 V tells you this contactor is sized for switching three-phase induction motors up to 4 kW — the standard duty class for squirrel-cage motors under IEC 60947-4-1. The 230-240 V AC coil means it pulls in on a standard control voltage; the 50/60 Hz label confirms it works on either mains frequency without derating. ## Panel Integration Screw terminals accept 0.2–2.5 mm² stranded or solid wire; strip length of 8 mm avoids whiskers under the clamp. The 3-pole main contacts handle the motor circuit; auxiliary contact blocks can be side-mounted for feedback or interlocking.","metaTitle":"Siemens 3RT1023-1AP80-0KR0-ZX95 Power Contactor, AC-3 9A, 4k","metaDescription":"Siemens 3RT1023-1AP80-0KR0-ZX95 power contactor, AC-3 9A, 4kW/400V, 3-pole, Size S0.
