32A 3POLES STAR DELTA CAM SWITCH O-Y-U 60 DEGREES-EMAS
The EMAS 32A 3-pole star-delta cam switch provides manual reduced-voltage starting for 3-phase AC motors to minimize high inrush starting current. Featuring sequential 0 (OFF) – Y (Star Start) – Δ/U (Delta Run) rotary control, double-break silver-alloy contacts, and an industrial 64\times64\text{ mm} front frame, it ensures smooth motor acceleration, low contact resistance, and reliable overload endurance in industrial automation panels.
