Micrologic Trip Units

Control Units for PowerPact™ P, R, and Masterpact NT, NW

Provide impeccable, electronic circuit protection with adjustable protection settings for maximum system coordination and flexibility. Sophisticated functionality, such as energy and power quality metering capabilities, is integrated in the more advanced trip units.

Micrologic Trip Units
  • Features

    The Micrologic® trip units make adding functionality very easy. They plug directly into Masterpact® NW, NT power circuit breakers or PowerPact™ circuit breakers and can be installed easily on site. This family of trip units includes four models with varying levels of functionality:

    Micrologic 3.0 and 5.0 -- basic overcurrent protection including long-time, instantaneous and optional short-time adjustments for overloads and short circuits.

    Micrologic 3.0A and 5.0A and 6.0A -- long-time, instantaneous and optional short-time adjustments, integrated ammeter and phase loading bar graph, LED trip indicator, zone selective interlocking with downstream breakers, optional ground-fault protection, optional Modbus® or Ethernet communication interface.

    Micrologic 5.0P and 6.0P -- long-time, instantaneous and short-time adjustments, advanced relay functions, inverse definite minimum time lag (Idmtl) long-time delay curve shaping for improved coordination, power monitoring and metering functions, Modbus or Ethernet communication interface, 6.0P adds ground-fault protection for equipment.

    Micrologic 5.0H and 6.0H -- includes all 5.0P and 6.0P functions, enhanced monitoring and metering capabilities, basic power quality (harmonic) measurement, waveform capture.
