AC-3 maximum switching rate is 750 operations per hour — that is the mechanical limit for reversing duty under load. AC-3e matches at 750 ops/h. Mechanical life is 10 000 000 cycles typical, so it outlasts most panel refreshes. Coil is screw-type terminals, 110 V at 50 Hz or 120 V at 60 Hz. The supplied contactor inside the assembly is 3RT2026-1AK60, which means the replacement contactor for the assembly is that exact unit — no guesswork on spare parts. ## Wire termination and environmental range Solid wire accepts 1 to 2.5 mm² on one pair and 2.5 to 10 mm² on the second pair. Stranded wire accepts 0.5 to 1.5 mm² and 0.75 to 2.5 mm². Shock resistance: 13.5 g / 5 ms and 8.3 g / 10 ms at AC, 15 g / 5 ms and 10 g / 10 ms at DC — relevant for mobile equipment or installations near rotating machinery.","metaTitle":"Siemens 3RA2326-8XB30-1AK6 SIRIUS Reversing Contactor, 11 kW","metaDescription":"Siemens SIRIUS reversing contactor assembly 3RA2326-8XB30-1AK6, size S0, 11 kW at 400 V AC-3, screw terminals, 35 mm DIN rail mount.

The 3RA2326-8XB30-1AK6 includes the mechanical interlock and both contactors in one assembly; swapping to a single contactor requires adding a separate reversing kit and interlock wiring."},{"question":"Will 3RA2326-8XB30-1AK6 drop into a panel specified around 3RT6028-1AB00?","answer":"No, not without rewiring. The 3RA2326-8XB30-1AK6 is a reversing contactor assembly with two contactors and mechanical interlock in one unit, while 3RT6028-1AB00 is a single contactor. The panel would need the reversing assembly's footprint and wiring plan, not the single contactor's."},{"question":"Where can I buy 3RA2326-8XB30-1AK6?","answer":"Sourced and quoted to order against an RFQ through independent distribution.
