Replacement motors and equipment that are pre-wired with Decontactor devices can be installed with plug & play simplicity, reducing change-out downtime by 50% and allowing
critical processes to get back online faster.


    • The need for hard-wiring during downtime is eliminated and mechanics can safely make & break the electrical connections.
    • There is no need to bring electricians to the site; their work to pre-wire replacements can be performed during non-downtime periods.
    • Advance verification of phasing on pre-wired replacement motors avoids problems and delays due to improper rotation.
  • Integral auxiliary contacts can eliminate the need to make & break secondary connections on control circuits.
