T2H160MA80/480-960FF 3P

The ABB T2H160 MA80/480‑960 FF 3P is a three‑pole molded case circuit breaker from the ABB SACE Tmax T2H series, designed for robust protection of low‑voltage electrical distribution systems. It uses an MA magnetic trip unit with adjustable instantaneous (short‑circuit) settings in the 80–960 A range for flexible protection coordination. The breaker offers reliable overload and short‑circuit protection, high breaking capacity, and fixed front terminals for easy installation in switchboards, motor control centers, and power distribution panels
