Features

  • Phase unbalance trips based on trip class selected minimizes temperature rise of the motor on a asymmetrical 3-phase system
  • Removable terminal block, terminal block can be removed without removing wires saves time for replacements
  • Phase loss protection trips in less than 3 sec protects motor burn out and minimizes motor heating up
  • Self-protected in short circuit condition (when used with proper fuses or motor starter protector-unlike bimetal overloads, this eliminates replacement of the overload heaters after short circuit)
  • Touch - safe terminals
  • Conformally coated circuit board resists against environmental conditions
  • Wide operating temperature range prevents nuisance tripping with temperature changes
  • Repeat accuracy <1% for more precise settings and reduced nuisance tripping
  • Class 48, frame size A1
  • FLA dial with wide adjustment 4:1 ratio provides wide range, reduces inventory
  • Touch safe terminal protects against accidental touching of live circuits
  • Trip classes- 5, 10, 20 or 30 selectable by DIP switches field changeable reduces time and inventory suitable for light, normal and heavy starting conditions
  • Self-powered no outside source required-reduce cost for external power supply
  • Trip indicator visible-save time, faster to identify overload trip
  • Test button tests electronics tests the complete electronic functions including the trip mechanism increases up time
  • Ground fault trips 60% of motor current provides optimum system protection of motors against high resistance short circuits or ground faults due to moisture, condensation, damage of insulation or any other reason
  • Ambient insensitive-prevents nuisance tripping
  • No heaters required-saves cost and eliminates time for installation of heaters
  • 3-phase, B600/R300 contact
  • Thermal memory prevents re-starting motor when it is still hot
