It is rated for AC-3 and AC-3e duty at 38 A up to 440 V, making it suited for switching three-phase squirrel-cage motors in that current class. The contactor also carries an AC-1 utilisation category rating for resistive load applications. It is designed for plate or DIN-rail mounting and carries an IP2X degree of protection, meaning it is protected against access to hazardous parts with a finger but is not sealed against moisture or dust ingress — it belongs inside a control panel or enclosure.
It also complies with GB/T 14048.1, GB/T 14048.4, and GB/T 14048.5 for the Chinese market, and with EN/IEC 60335-1 Clause 30.2 and EN/IEC 60335-2-40 Annex JJ for glow-wire / fire resistance in appliance applications.
