ABB T1N-90A-3P-480-600Y-347V-AC Circuit Breaker

ABB SACE Tmax T1N 90A 3P AC circuit breaker is a molded‑case protection device designed for 3‑phase power systems in the 600Y/347V class, with a 90‑amp frame that protects feeders and equipment in industrial and commercial distributions. This three‑pole unit is sized for use in panelboards and distribution boards, and its exact designation—T1N-90A-3P-480-600Y-347V-AC—specifies the 3‑pole configuration, 90 A rating, and the 480/600Y with 347V reference common to 600Y/347V systems. It employs a thermal‑magnetic trip mechanism to interrupt faults quickly, providing reliable protection against overloads and short circuits in circuits powered by 50/60 Hz systems. Typical applications include main or branch circuit protection in industrial control panels, motor feeders, and electrical distribution setups where a robust MCCB is required to safeguard conductors and connected equipment. The Tmax T1N family is designed for compatible installation within ABB SACE footprints and accessories, offering a compact, dependable solution for high‑voltage low‑voltage distribution networks that demand precise overcurrent protection at the 90 A level.
