The ABB XT2N 160 TMA63/630 3‑pole MCCB is a molded‑case circuit breaker (MCCB) from the ABB SACE Tmax XT series, designed for protection of electrical circuits and machinery. It provides overcurrent and short‑circuit protection using a thermal‑magnetic (TMA) trip unit. The breaker is fixed (non‑withdrawable), features front‑terminal connections (“F F”), and is intended for installation in industrial and commercial low‑voltage power distribution systems.
