It is rated for AC-1 utilisation category at 25 A up to 415 V, meaning it is designed for switching resistive loads — heaters, lighting banks, or other non-inductive circuits — in control panels. The IP2X degree of protection means the enclosure resists finger contact but is not sealed against dust or moisture — it belongs inside a cabinet, not on a washdown line.
The 25 A AC-1 rating is the headline number, but note the duty: AC-1 is resistive load. If your circuit drives motors, transformers, or other inductive loads, the contactor's AC-3 or AC-4 rating would be lower — this part does not carry those categories in its listing. The 4NO pole configuration is fixed; there is no changeover (NC) pole on this variant. The non-overlap time of 1.5 ms on both energisation and de-energisation, guaranteed between NC and NO contacts, is a safety-relevant parameter for interlocking circuits where a make-before-break condition must be avoided. The protective treatment TH (pollution degree 3) per IEC 60068 means the contactor is treated for tropical humidity and moderate industrial atmospheres — condensation and conductive dust are expected in the environment, and the part is designed to withstand them without conformal coating.
