There are two very simple and cost effective solutions to upgrade all Masterpact M/MC/MP to new technology Masterpact NW/NT breakers, extending the useful life of existing asset and insure parts availability.

Two solutions are:

  • “Plug and Play” solution: allows a factory modified and adapted Masterpact NW drawout breaker to be installed into an original Masterpact MP/MC/M cradle. 
    Note: This option only applies to M series breakers that have a continuous current rating of 3000 amp or less and the existing breaker has an interrupt rating of 65KA (up to 2000A) or 100KA(2500/3000A) or less.
  • Retrofill kits: allows Masterpact NW fixed and drawout cradles to be retrofit into an existing installation of Masterpact MP/MC/M devices. 

Benefits of Masterpact MP/MC/M Upgrade:

  • Provides latest technology in protection, metering, monitoring and communication functions with the Micrologic™ trip units
  • Enhances electrical system reliability and maintain breaker ratings
  • Reduces downtime for installation, compared to new equipment
  • Lowers maintenance and operating expenses
  • Eliminates the need to locate and stock obsolete Masterpact MP/MC/M circuit breaker parts
  • Minimizes environmental impact as Masterpact NW breaker uses non-polluting and recyclable materials, and is manufactured in ISO 14001 certified factories
