Schneider Electric FDA34100 Molded Case Circuit Breaker

Schneider Electric FDA34100 Molded Case Circuit Breaker is a 100-amp, 3-pole protective device rated for 480Y/277 VAC. As part of the Square D/Schneider Electric FDA family, it is designed for use in three-phase distribution schemes found in commercial and light-industrial panels. With a 480Y/277 VAC rating, it supports line-to-line voltage of 480 V and line-to-neutral voltage of 277 V typical in North American industrial power systems. This MCCB provides overcurrent protection for feeders and branch circuits, helping to prevent damage from overloads and short circuits. The 3-pole configuration protects all three phases simultaneously, enabling coordinated protection in three-phase installations, and its molded-case construction supports durable performance in demanding environments. Common applications include service panels, distribution boards, and machine control circuits in commercial or light-industrial settings where a 100 A, 480Y/277 V protective device is appropriate.
