The AC-1 rating (resistive) will be higher, but for a motor circuit, the AC-3 number is the one that decides if this part fits your starter. The 48 V AC coil at 50 Hz is fixed — no dual-frequency or DC coil option here, so verify your control transformer matches. The 1NC auxiliary is built in; if you need more, you'll add a side-mount block.
Integration and mounting notes
The IP2X finger-safe front cover is standard for enclosed panels. Ambient operation is rated -5 to 55 °C, with storage down to -60 °C and up to 80 °C. Altitude derating kicks in above 3000 m — below that, no reduction needed.
Compliant with EN/IEC 60947-1, -4-1, -5-1 and the corresponding GB/T standards for China. Also tested to EN/IEC 60335-1 Clause 30.2 and EN/IEC 60335-2-40 Annex JJ for appliance applications. The mechanical robustness specs — 1.5 Gn vibration open, 3 Gn closed, 10 Gn shock closed — give you confidence in high-vibration installations like compressors or conveyors.
