The ABB T2S160 TMD63/630 FF 3P is a three‑pole molded case circuit breaker (MCCB) from ABB’s Tmax S (T2S) protection range. It provides adjustable thermal‑magnetic protection using a TMD trip unit with a setting range of 63–630 A, offering reliable overload and short‑circuit protection for low‑voltage electrical distribution systems. The front‑fixed‑terminal design simplifies installation in distribution panels and control boards, and the breaker is suitable for industrial, commercial, and electrical power protection applications.
