Ratings to confirm: the source records 18 A as a contact-current rating and 690 V AC under both supply-voltage and contact-voltage headings. These headings do not establish an auxiliary-contact load rating or a powered coil supply. A separate “10A” tag is unexplained in the available description; do not use it to select the overload range.

Hazardous-area suitability is unverified. Previous tags included ATEX, Ex, Ex II (2) GD and “explosion proof”, but supporting certification for this unit is not provided. Do not rely on those tags as approval for hazardous-area use. Green Premium/Better World claims in the source have also not been verified for this stock item.

Confirm the exact unit markings, compatible contactor, electrical duty, condition and any required certification with MIS before ordering.
