Siemens Marq 21 NEMA Size 0 Soft Starter - 480V/3P

Soft Starter | NEMA 0 | 10HP | 480V/3P | Reduced Voltage Starting

This Siemens Marq 21 NEMA Size 0 soft starter MCC bucket provides controlled voltage ramp-up for smooth motor acceleration, field-proven across thousands of installations. Rated for 10HP 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, allowing hot-swappable serviceability without de-energizing the MCC lineup. Widely specified for building automation systems, conveyor networks, and packaging lines, the Marq 21 soft starter bucket enables quick replacement and serviceability without disrupting adjacent MCC units. UL 845 listed and NEC Article 430 compliant for immediate installation.
