For a reversing starter, this covers the forward and reverse contactors in one package — the same 18 A applies to both directions. The 24 VDC coil is standard for PLC-driven panels where 24 V control power is already on the DIN rail. The 1NO-1NC auxiliary contacts per contactor give the panel builder one feedback pair per direction without adding a separate auxiliary block. That keeps the depth on the rail tight and reduces the parts count for the reversing interlock circuit.","metaTitle":"Siemens 3RA9012-5AN14 Reversing Contactor, 18 A, 24 VDC","metaDescription":"Siemens 3RA9012-5AN14 reversing contactor, 3-pole, 18 A, 24 VDC coil, 1NO-1NC aux contacts.
