Molded-case Circuit Breakers (MCCB)

Description

Molded-case circuit breakers are utilized to open/close low-voltage circuits and protect wiring by automatically closing circuits when overloading or short-circuiting occurs.

NF-C Series Economy Type

This basic model has excellent cost performance. Standard products range from 30 to 800A frames.

NF-C Series Standard type

NF-H Series Hight-performance Type

This standard model lineup, with products from 32A to 1600A frames, can be used for a wide range of applications. (H Series: 63A-800A frames)

NF-U Series Ultra Current-Limiting Type

Realizing the world~s maximum breaker capacity of 200kA, this high breaking capacity/high earth leakage circuit breaker is the optimum model for backup shutdown.
