Mitsubishi Electric MSO-T21DL Delay-Open Magnetic Starter (0.24-15A)

Mitsubishi Electric MSO-T21DL Delay-Open Magnetic Starter (0.24-15A)

The Mitsubishi Electric MSO-T21DL is an MS-T/N series delay-open magnetic starter that keeps the motor circuit closed through momentary power failures.

Key features

  • Holds the contactor closed for 2 (+2/-1) s during momentary power failures or voltage dips
  • Capacitor-backed coil circuit - no re-closing operation needed after the dip, load keeps running
  • For lighting, building automation and other circuits that must ride through brief outages
  • Rated AC-3 capacity 4 / 7.5 / 7.5 kW at 220/440/550V; heaters 0.24A-15A
  • Operation coil AC100V (100-110V) or AC200V (200-220V); main-circuit rated voltage must be specified at order
