AC auxiliary ratings include 230 V at 6 A and 400 V at 3 A. The operating range at 50 Hz and 60 Hz is 0.8 to 1.1 times the rated control supply voltage, which means the coil holds in from about 19.2 V to 26.4 VDC at nominal 24 V. ## Short-Circuit Coordination and Terminal Data The main circuit terminals accept screw-type connections: 2x (0.25 to 2.5 mm²) solid, 2x (1 to 2.5 mm²) stranded, 2x (2.5 to 6 mm²) stranded, and up to 2x 10 mm² maximum. AWG equivalents are 2x (16 to 12), 2x (14 to 10), and 1x 8.","metaTitle":"Siemens 3RT1023-3AK60 SIRIUS Power Contactor, S0, 24 VDC 10","metaDescription":"Siemens 3RT1023-3AK60 SIRIUS power contactor, size S0, 24 VDC coil 10 A, rated 4 kW at AC-2 400 V, 8.5 A AC-4.

Availability and current pricing are confirmed at quote time — no stock count or lead-time figure is published here."},{"question":"What is the depth of 3RT1023-3AK60?","answer":"The depth is 90 mm. Width is 45 mm and height is 85 mm, so it occupies a single 45 mm module on a 35 mm DIN rail."},{"question":"What solid conductor sizes does 3RT1023-3AK60 accept?","answer":"The main circuit terminals accept 2x (0.25 to 2.5 mm²) solid conductors.

The key difference is the coil voltage: 3RT1023-3AK60 uses a 24 VDC coil rated at 10 A, while 3RT1023-1AL20 uses a different coil voltage. Verify the control circuit voltage before substitution."},{"question":"What compliance documentation does Siemens provide for 3RT1023-3AK60?","answer":"As a SIRIUS product, Siemens provides a declaration of conformity to relevant EU directives (Low Voltage Directive, EMC Directive) and the manufacturer's CE marking.
