Pollution degree 3 and climate withstand per IEC 60947-1 Annex Q category D mean it can live in industrial environments with moderate condensation and conductive dust. Physical footprint: 4.7 in wide, 4.8 in tall, 4.7 in deep. Operating temperature range -40 to 140 °F (-40 to 60 °C), with derating above 140 °F up to 158 °F.
Reversing contactor uses a mechanical interlock (internal via the preassembled busbar). Wire the two contactor coils separately; the reversing logic is handled by your control circuit (typically a pair of interlaced contactors with NC/NC auxiliaries). Dimensions match the TeSys D frame: fits standard DIN-rail or screw-mount panel patterns used by other TeSys D contactors. Keep the ambient temperature derating in mind if installing near other heat sources inside a sealed cabinet. Flame retardance V1 (UL 94) and glow-wire tested to 1562 °F (850 °C) per IEC 60695-2-1 — no additional fire barrier needed for most industrial panel builds.
