The ABB T2S160 TMD63/630 FF 3‑pole MCCB is a fixed (non‑withdrawable) low‑voltage circuit breaker designed to provide over‑current and short‑circuit protection for three‑phase electrical circuits. It features a thermal‑magnetic (TMD) trip unit with adjustable short‑circuit instantaneous setting. The breaker is intended for industrial or commercial installations, suitable for motor circuits, switchboards or general power‑distribution panels requiring configurable protection and high breaking capacity. Front‑terminal (“FF”) arrangement enables easy wiring and panel integration.
