It mounts directly to a Size S2 contactor and protects three-phase AC/DC motor circuits up to 690 V, 50–60 Hz. Front face carries IP20 protection; the screw terminals are IP00, so plan enclosure sealing accordingly.
Body footprint is 118 mm deep by 55 mm wide by 105 mm tall. Side clearance to grounded parts needs 6 mm minimum.
Main and auxiliary/control circuits use screw-type terminals. Main terminals accept 2× (0.5–1.5 mm²) solid/stranded or 2× (0.75–2.5 mm²) with ferrule, torqued to 3–4.5 N·m.
Operational temperature range is -20 to +55 °C, with 0–90 % relative humidity. Storage/transport range extends to -25 to +70 °C. Installation altitude is limited to 2 000 m above sea level.
