- "TeSys D changeover contactor, 4 poles (4NO), for non-inductive load applications up to 40A/690V AC-1. It provides 24V DC coils, 2NO+2NC built-in auxiliary contacts (NC mirror contacts), connection by screw clamp terminals. For operating rates until 3600 cycles/hour and environments until 60\u00b0C, it procures high reliability and durability. Compact (90mm width), DIN-rail mounting or screw fixing. With pre-wired changeover power connections, mechanical interlock (without electrical interlocking). Multi standards certified (IEC, UL, CSA, CCC, EAC, Marine), Green Premium compliant (RoHS/REACh)."
