Square D MG27345N Molded Case Circuit Breaker

The Square D MG27345N is a molded case circuit breaker (MCCB) in Square D’s MG family, designed to protect electrical circuits by interrupting current during overloads or short circuits. This model is a 2-pole device rated for 16 A and up to 480 V AC, featuring a D-curve trip characteristic for general-purpose protection against short circuits while accommodating normal load conditions. Thermal-magnetic trip action automatically opens the circuit when overloads occur, helping safeguard conductors and equipment in low-voltage distribution systems. The MG27345N’s compact two-pole design enables simultaneous isolation of both conductors in a single enclosure, a common arrangement for panel and distribution-board protection in industrial and commercial settings. Catalog number MG27345N identifies this specific 16 A, 2P, 480 V, D-curve breaker from Square D, a brand known for reliable, modular MCCB solutions within electrical distribution equipment.
