Mitsubishi Electric MSO-N125KPSR Saturable Reactor Magnetic Starter

The Mitsubishi Electric MSO-N125KPSR 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-N125 contactor with a TH-N120KPSR/TH-N120TAKPSR 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 30 / 60 / 60 kW at 220/440/550V; Ith 150 A
Heater designations 42A-105A; coils AC24V, AC48V, AC100V, AC200V, AC300V, AC400V, AC500V
3-element (2E) relay adds open-phase protection
