Fuji Electric Contactors

Fuji low-voltage contactors and starters are available in a broad choice of types, from high-performance to economy, for all consumer and industrial needs. For standard applications, we offer the high-performance SC series. We offer the economical F series for light industrial use, the SB series dedicated to DC circuits, the SJ series for direct driving by transistors, and the SS series with long service-life noise-free solid-state contactors.

SC and SW series
Standard type magnetic contactors and starters
The SC series is a range of long service-life and high-performance contactors. SC-03 to SC-5-1 small-frame contactors provide snap-on fitting of numerous optional units, such as auxiliary contact blocks, coil surge suppressors, and operation counters.
Field modifications are quick and easy to make.
Type SC-4N and above contactors come with an IC-controlled SUPER MAGNET coil, which operates from both AC and DC sources, to eliminate burnt coils and contact chattering caused by voltage fluctuation.

SJ series
High sensitivity contactors and starters
The SJ series is a range of compact and lightweight DC-operated AC contactors employing a special polarized electromagnet. With greatly reduced power consumption, the SJ series contactors can be directly operated by transistor output, such as from a programmable controller or photoelectric sensor. The auxiliary contact is bifurcated for added contact reliability, so it can even be used in 5V DC, 3mA circuits. Despite their compact geometry, the SJ series contactors can also be used in 440V AC circuits.

SB series
DC magnetic contactors
We developed the SB series DC contactors from our SC series AC contactors. Applications include opening and closing DC circuits and controlling DC motors. They permit switching of DC loats up to 550V DC, 360A. There are two main contact arrangements available: the 2NO type and the 2NO + 1NC type, which has one NC contact for dynamic brake circuits. Type SB-5N and above contactors come with an IC-controlled SUPER MAGNET coil for improved operational stability.

FMC and FMS series
Definite purpose contactors and starters
The FMC series contactors are compact and economical contactors designed for use in consumer appliances with relatively low switching frequencies. Typical applications include air conditioners, industrial washing machines, heaters, compressors, driers, and fans. Contactor pickup voltage is 75% of the rated voltage. FMC-0 is available with tab and printed board terminals, as well as self-lifting screw terminals.

SS series
Solid-state contactors
The SS series contactors employ a semiconductor that can withstand both high voltage and large overcurrent when making and breaking load circuits. The completely contactless design gives high performance, including long service life and noise-free operation. Applications include frequent making and breaking for motors, heaters, and similar circuits. A built-in surge absorbing varistor and CR circuit to protect the SSC from surges when switching inductive loads, and surges from external circuits.
