Toshiba MCCB-NJ225F Molded Case Circuit Breaker

The Toshiba NJ225F Molded Case Circuit Breaker is a 225 A, 3-pole MCCB designed for panel-mount protection in low-voltage, three-phase power systems. It uses a thermal-magnetic trip unit within a 225 AF frame to deliver overload and short-circuit protection for motors and motor control equipment in industrial settings. Commonly installed in motor control centers (MCCs), distribution panels, switchboards, and industrial machinery, the NJ225F supports 50/60 Hz operation and is suitable for equipment across HVAC systems, pumps, compressors, and factory automation lines. OEMs, maintenance teams, and system integrators rely on this device for replacements, panel maintenance, upgrades, and retrofits, with compatible Toshiba alternatives including NJ250F, NJ225S, and NJV225F.
