Within our Moulded Case Circuit Breakers range, the A2N 250 TMF 150-1500 3P F F combines a 400 A service rating with a 36 kA Icu for dependable overload and short-circuit protection. Its calibrated TMF curve supports selective coordination across feeders and motor circuits while keeping wiring accessible. For projects that pair protection with drive systems and motor feeders, integrate with our ARC-engineered motors and control systems to streamline performance and lifecycle support.
