Siemens Marq 21 15A/15A Dual Breaker Feeder - 480V/3P
Dual 15A | 480V/3P | 100A Frame | Independent Circuits
This Siemens Marq 21 15A/15A dual breaker feeder consolidates two independent feeder circuits into a single MCC bucket, built to withstand harsh industrial conditions. Rated at 480V with dual 100A frame breakers, it maximizes panel density while maintaining full isolation between circuits. Each breaker operates independently, minimizing maintenance costs while maximizing equipment longevity. Perfect for steel mills, cement plants, and large-scale commercial buildings, 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.
