ABB S5N300TDDAS8 Molded Case Circuit Breaker

ABB S5N300TDDAS8 Molded Case Circuit Breaker is a 300 A, 600 V, three‑pole MCCB from ABB’s S5N family, engineered to protect industrial power feeders and panelboards. It delivers a 22 kA short‑circuit interrupting capacity and is equipped with an auxiliary switch plus a shunt trip for remote protection and status signaling. The molded‑case design provides compact, rugged protection suitable for dense panel layouts and control panels in industrial environments. This configuration integrates both local manual control and remote tripping capability, enabling coordination with plant protection schemes and safety interlocks while preserving simplicity in wiring and monitoring. Applications include distribution panels and MCC assemblies where reliable, high‑capacity protection is required and where remote trip signaling and auxiliary status contacts are beneficial for integration with centralized protection logic.
