The Mitsubishi Electric MSO-N400DL 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 110 / 200 / 200 kW at 220/440/550V; heaters 105A-330A
Operation coil AC100V (100-110V) or AC200V (200-220V); main-circuit rated voltage must be specified at order
