General information

Bar contactors – up to 8500A and 1500 V AC/DC

Lenoir Elec bar contactors are exceptionally modular. All their constitutive parts are easily replaceable and thus offer many possibilities:

  • Assembly of main poles in variable number, with similar or different ratings, with different current nature, of closing or of opening type, with or without mechanical overlapping, with or without magnetic blowout.
  • Assembly of auxiliary contacts in significant quantity, instant normally open or normally closed, with or without overlapping, with blowout (for DC selfic control circuits) or without blowout, delayed on opening or on closing of contactor.
  • Assembly of a mechanical latching with single or double electrical release with or without tripping coil(s) auto-protective system.
  • Possible mechanical interlock with one or several contactors of the same calibre or of different calibre, in vertical position or back-to-back.
  • Possible adaptation of the centre-to-centre distance to the assembly conditions.
  • Possible lock condemnation of the contactor in the open position (Ronis type, Profalux,…)

The qualities of these contactors are numerous: high mechanical electrical and endurance, reliability during intensive use, inductive breaks in AC and DC current and under high power, flexibility of design and in use, extended lifetime, numerous auxiliary contacts,… Such assets allow LENOIR ELEC bar contactors to cover a wide range of requirements which block contactors or power electronics, by design, cannot meet.
