Schneider Electric 997326 Three Phase Circuit Breaker

Schneider Electric's Square D 997326 is a three-phase circuit breaker designed for industrial and commercial power distribution. This 3-pole unit is rated for 200 A and supports systems up to 600 V, making it suitable for protecting three-phase feeders in a wide range of electrical installations. As a Schneider Electric product (Square D brand), the 997326 provides overcurrent protection by interrupting current during overload or short-circuit events, helping to prevent damage to wiring, motors, and downstream equipment. The 3‑pole configuration ensures simultaneous disconnection of all three phases, enhancing safety and reliability in three-phase circuits. This part number denotes a high-current, three-pole protection device intended for use in panels and switchgear that accept 3‑pole breakers in the 200 A class and 600 V maximum voltage. In practice, it is used wherever a robust, compliant 3‑phase protection solution is required in distribution panels, service equipment, or other enclosure-based installations. By specifying 997326, technicians identify a precise Schneider Electric Square D component designed to meet the needs of 200 A, 3‑phase, 600 V applications, providing straightforward integration into compatible electrical systems.
