Each contactor carries 2NO-2NC auxiliary contacts — the NO pair signals the PLC that the main poles have closed; the NC pair provides a hardwired interlock against both contactors pulling in simultaneously. The 24 VDC coil includes a factory-fitted suppressor (typically a freewheeling diode or varistor), which protects the DC control supply from voltage spikes when the coil de-energises — critical for PLC-sourced 24 VDC outputs that lack built-in flyback protection. At 80 A, this assembly suits reversing motor loads up to roughly 37 kW at 400 V AC-3 duty, depending on the motor's full-load current and the ambient temperature derating curve. ## Lifecycle status and sourcing posture No official successor or replacement order code is on file; this is the current catalogue part for a reversing contactor assembly at this rating and coil voltage.","metaTitle":"Siemens 3RA9012-5AX24 Reversing Contactor, 24 VDC, 80 A","metaDescription":"Siemens 3RA9012-5AX24 reversing contactor assembly, 3-pole, 24 VDC coil, 80 A, with 2NO-2NC aux contacts and coil suppressor.
