Siemens Marq 21 50A/50A Dual Breaker Feeder - 480V/3P
Dual 50A | 480V/3P | 100A Frame | Independent Circuits
This Siemens Marq 21 50A/50A dual breaker feeder consolidates two independent feeder circuits into a single MCC bucket, engineered for maximum reliability. Rated at 480V with dual 100A frame breakers, it maximizes panel density while maintaining full isolation between circuits. Each breaker operates independently, ensuring code-compliant installations with streamlined wiring. Perfect for oil and gas operations, food processing plants, and automotive assembly lines, this dual-compartment design cuts installation costs by reducing the total number of bucket slots required. The Marq 21 architecture ensures backward compatibility with existing MCC lineups, enabling seamless capacity upgrades. Meets UL 845 and NEC Article 240/430 standards.
