Square D Model 4 NEMA Size 1 Soft Starter - 600V/3P
Soft Starter | NEMA 1 | 20HP | 600V/3P | Reduced Voltage Starting
This Square D Model 4 NEMA Size 1 soft starter MCC bucket provides controlled voltage ramp-up for smooth motor acceleration, purpose-built for critical infrastructure. Rated for 20HP at 600V 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, simplifying inventory management with standardized form factors. Widely specified for airport facilities, hospital critical power, and campus electrical systems, the Model 4 soft starter bucket enables quick replacement and serviceability without disrupting adjacent MCC units. UL 845 listed and NEC Article 430 compliant for immediate installation.
