Mitsubishi Electric MSO-N300KPSR Saturable Reactor Magnetic Starter

Mitsubishi Electric MSO-N300KPSR Saturable Reactor Magnetic Starter

The Mitsubishi Electric MSO-N300KPSR is an MS-T/N series open-type magnetic starter with a saturable-reactor thermal overload relay for motors with long starting times.

Key features

  • Combines an S-N300 contactor with a TH-N400RHKPSR saturable-reactor thermal overload relay
  • Saturable reactor limits heater current above approx. 200% so long starting does not cause nuisance tripping
  • For motors with long acceleration (high-inertia loads) and intermittent duty, starting current 5-8x FLC
  • Rated AC-3 capacity 75 / 150 / 160 kW at 220/440/550V; Ith 350 A
  • Heater designations 105A-250A; coils AC48V, AC100V, AC200V, AC300V, AC400V, AC500V
  • 3-element (2E) relay adds open-phase protection
