Mitsubishi Electric - ET-N150 Electronic Motor Protection Relay (150A frame, 40 to 150A Setting Range)

Mitsubishi Electric - ET-N150 Electronic Motor Protection Relay (150A frame, 40 to 150A Setting Range)

Mitsubishi Electric MS-T/N series ET-N150 electronic motor protection relay that detects overload including locked rotor, open phase including current imbalance, and reverse phase conditions during AC motor starting and running. 150A frame covering current settings 40 to 150A across 1 setting designation, with a setting range of three to four times the minimum scale.

Key features

  • A protection mode switch selects overload only, overload plus open phase, or overload plus open phase plus reverse phase, and the overload operating time is selectable between 3, 5, 7, 15 and 30 seconds at 600 percent of the setting current
  • Independent 1a1b output contacts can be used on different voltage circuits, indicators show power, overload, open phase and reverse phase status as well as load run and stop, and a self diagnosis function trips the relay on an internal fault
  • Operating voltage AC100V or AC200V with 85 to 110 percent tolerance, manual reset, main circuit terminal connection with no need to wind the main circuit conductor
