Fuji IEC manual motor starters provide high switching capacity while integrating the functions of a molded case circuit breaker (MCCB) and a thermal overload relay. This compact MMS solution offers adjustable thermal-magnetic tripping in 3-phase configurations up to 63A at voltage ratings up to 600 VAC.
AutomationDirect has worked with Fuji Electric to offer a complete line of electric motor controls.
AutomationDirect now offers Fuji's DUO series line of motor contactors, overload relays, and manual motor starters, as well as their Odyssey line of large contactors and overload relays. These motor controller products provide complete electric motor control solutions up to 300 horsepower at 480 VAC.
Fuji's DUO line of motor controls components are fully integrated and can be used to build a conventional contactor/ overload starter, or the Fuji manual motor starter (MMS) can be combined with an SC-E series contactor for a combination motor starter. Since the MMS is UL listed for Category E self-protected motor control, it can be used for motor branch circuit protection without the need for additional motor protection such as fuses or molded case circuit breakers.
NOTE: Changes in UL 508 now require that short circuit trip contacts should be added to the manual motor starter (MMS), and a terminal cover should be added to the 32 amp frame size MMS.
AutomationDirect offers the MMS in a 32-Amp version with a 45 mm frame width and a 63-Amp version with a 55 mm frame width.
Both manual motor starter versions have high breaking capacities, up to 100,000 Amps in some ranges. The MMS combination motor starters can accommodate electric motors up to 40 horsepower at 480 VAC. The conventional motor starters in the DUO line can accommodate motors up to 100 horsepower at 480 VAC.
The DUO line is available in 24 VAC, 24 VDC, 120 VAC, and 240 VAC coil versions.

The BM3 Series manual motor starters (MMS) provide new circuit breakers for motor use that provide optimal protection by integrating the functions of a molded case circuit breaker (MCCB) and thermal overload relay into a highly compact unit. The BM3 Series manual motor starters (MMS) provide magnetic short circuit protection. This short circuit trip rating is approximately 13 times the FLA rating of the overload function.
Thermal overload relay functions include:
Innovative technology has integrated the functions of a molded case circuit breaker (MCCB) and a thermal overload relay. The advantages of this new technology include:
Described below are typical problems encountered in conventional systems, along with the solution offered using the MMS system.
A Manual Motor Starter (MMS) provides reliable protection for overloading and short-circuiting in motor branch circuits. We offer compact motor starters with a 55mm width for rated currents to 63A and motor capacities to 40 Hp at 480 VAC. Features include:
A wide variety of accessories enables a flexible response to changes in specifications. Snap-on fittings speed up mounting. Accessories like auxiliary contact blocks, shunt trip devices, and undervoltage trip devices have been standardized for the 45 mm and 55 mm wide frame sizes of the BM3R and BM3V. Enclosures and external operating handles are available as optional accessories. Accessories are easily mounted.
