Siemens Model 90 NEMA Size 5 Soft Starter - 480V/3P
Soft Starter | NEMA 5 | 250HP | 480V/3P | Reduced Voltage Starting
This Siemens Model 90 NEMA Size 5 soft starter MCC bucket provides controlled voltage ramp-up for smooth motor acceleration, engineered for maximum reliability. Rated for 250HP at 480V three-phase, the integrated solid-state soft starter eliminates mechanical stress by gradually increasing motor voltage, reducing inrush current by up to 70 percent. Features adjustable ramp times, current limiting, and built-in motor protection, minimizing maintenance costs while maximizing equipment longevity. Widely specified for semiconductor fabrication, renewable energy installations, and municipal utilities, the Model 90 soft starter bucket enables quick replacement and serviceability without disrupting adjacent MCC units. UL 845 listed and NEC Article 430 compliant for immediate installation.
