Fuji Electric Circuit Breakers

Compact and reliable earth leakage and molded case circuit breakers for any application

Molded case and earth leakage Fuji Electric circuit breakers combine high reliability with low-cost. With a variety of types and models to choose from, there is a Fuji circuit breaker to fit your application.

Fuji Electric circuit breakers meet today's demands for reliable, cost-effective, and easy-to-use power supplies. Compact and reliable, circuit breakers from Fuji are easy to install and maintenance-free. Featuring a time-delay and instantaneous trip mechanism, Fuji circuit breakers offer a highly sensitive leakage current device for a quick response to ground faults.

Each circuit breaker from Fuji features a three-step sensitivity to fault currents and a three-step selection of tripping time. The improved current-limiting mechanism features high-speed contact opening and a short arcing time. In addition, the earth leakage Fuji circuit breaker has a calibrated ambient temperature of 40°C.

Molded case Fuji Electric circuit breakers employ a new current-limiting mechanism, which along with a dual-latching mechanism, will interrupt current faster at higher capacities.

Models of Circuit Breakers from Fuji Electric

There are a wide variety of circuit breakers to best suit your needs, from economical to high performance.

• The "E" Series line of compact, economical circuit breakers is ideal for circuits with relatively low short-circuit Rand currents.
• The "S" Series' new and unique current-limiting mechanism provides a surprisingly high current interrupting capacity for a compact breaker.
• The "H" Series features an excellent current-limiting mechanism and an enhanced method of arc-extinguishing to achieve a higher current interrupting capacity.
• BU Series circuit breakers have a compact construction and are easily mountable in standard-type lighting panelboards and switchboards. They also employ a built-in HSS-trip mechanism, which permits series-rated systems for cost effectiveness.
