Mitsubishi Electric 3-Pole Molded Case Circuit Breaker (MCCB) NF400-CP 600VAC

The Mitsubishi Electric NF400-CP is a 3-pole molded case circuit breaker (MCCB), also designated a No-Fuse Breaker, rated at 400 amperes and 600VAC with a frequency range of 50 to 60Hz. The impulse withstand voltage (Uimp) is rated at 8kV as confirmed on the nameplate. This unit is the economy-class (CP series) variant of the Mitsubishi NF400 frame and is manufactured in Japan. The breaker is mounted inside a metal enclosure panel with a push-to-trip test button visible on the face of the breaker. The handle is currently in the OFF position. The NF400-CP is a discontinued model per manufacturer records; replacement availability on the open surplus market makes units in this condition relevant for machine tool, industrial panel, and distribution system maintenance and retrofit applications. The frame accepts 400A maximum current at the 3-pole configuration shown. Short circuit capacity is 13kA at 440VAC per the nameplate data visible on the breaker body. The enclosed panel format provides a self-contained, ready-to-mount assembly suitable for direct integration into an electrical cabinet or wall-mounted installation.
