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.
