The ABB T5N630 TMA500/2500‑5000 FF 3P is a three‑pole molded case circuit breaker (MCCB) from the ABB SACE Tmax T5N series, designed for industrial and commercial power distribution protection. It provides fixed mounting three‑pole protection of electrical circuits and equipment against overload and short‑circuit conditions, with a thermal‑magnetic trip unit (TMA) that allows adjustable short‑circuit release settings. This MCCB is suitable for use in switchboards, motor feeders, and distribution panels where robust circuit protection and high interrupting capacity are required.
