IEC Electrical Motor Control

As control systems become more compact and the need for more cost-competitive industrial motor control options arise, an IEC motor controller is the answer. Complying with the stringent International Electrotechnic Commission (IEC) 60947 standards, our IEC motor controller series of contactors and starters offer convenience and cost-effectiveness in one package.

Complete line of FUJI Industrial Motor Control products

AutomationDirect has partnered with Fuji Electric to carry Fuji's DUO series line of motor contactors, overload relays, and manual motor starters (MMS), as well as their Odyssey line of large contactors and overloads featuring Super Magnet™ coil technology. These offerings provide complete motor control solutions up to 300 horsepower.

The conventional starters in the DUO line can accommodate motors up to 100 horsepower at 480 VAC, while MMS combination starters can accommodate motors up to 40 horsepower at 480 VAC and are UL Type E listed.

The Odyssey Series of contactors come in sizes up to 300 horsepower at 480 VAC. The DUO series contactors are available in 24 VAC, 24 VDC, 120 VAC, and 240 VAC coil versions. The Odyssey series of contactors is available with 24 V, 120 V, and 240 V Super Magnet coils that can be powered with AC or DC.

A complete line of accessories is also available.

GH Series and Cutler-Hammer* motor control components
Existing customers using the GH-Series and Cutler-Hammer products can continue to purchase these components at our always-low prices. The GH-Series IEC contactors provide switching capacities to 100 thermal amps. Combine a GH-Series contactor with an adjustable bi-metallic overload relay or a motor starter/ protector for a complete motor control solution.

The Cutler-Hammer AE16 Freedom Series IEC Contactors are available in a 45 mm frame size that can handle up to 20 hp at 460 V. They are DIN-rail mountable in either the vertical or horizontal upright position. The Cutler-Hammer IEC Starters are full voltage magnetic starters for polyphase induction motors. These starters also protect the motor against running or stalled overcurrents.

*Cutler-Hammer parts are available for sale in North America only.

A complete line of accessories is also available.

**************************************************************

The DUO line of components are fully integrated and can be used to build a conventional contactor/ overload starter, or the new Fuji manual motor starter (MMS) can be combined with an SC-E series contactor for a combination 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 protection such as fuses or molded case circuit breakers. NOTE: Recent changes in UL 508 now require that short circuit trip contacts should be added to the 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 MMS versions have high breaking capacities, up to 100,000 Amps in some ranges. The MMS combination starters can accommodate motors up to 40 horsepower at 480 VAC. The conventional starters in the DUO line can accommodate motors up to 100 horsepower at 480 VAC.

The larger contactors feature the Super Magnet™ coil for greater reliability and positive pick-up and drop-out. The Super Magnet™ combines an integrated circuit with a conventional coil for superior performance. Drop-out and chattering is eliminated during high inrush start-ups. The Super Magnet™ accepts AC or DC coil control voltage in the respective ranges. Reversing kits are available for the SC-E series contactors. A complete line of accessories is also available.

The Odyssey series of contactors and overloads also feature the Super Magnet coil and come in sizes up to 300 horsepower at 480 VAC. The Odyssey series contactors are available in four sizes with overloads to match any motor up to 300 horsepower.

Both the SC-E series products and Odyssey lines are available in 24 VAC, 24 VDC, 120 VAC, and 240 VAC coil versions.

Contactors are available in the following ranges:

• 9-25 Amp (SC-E02 to SC-E05 Series)
• 32-50 Amp (SC-E1 to SC-E2S Series)
• 65-80 Amp (SC-E3 and SC-E4 Series)
• 105-150 Amp (SC-E5 to SC-E7 Series)
• 180-360 Amp (Odyssey 3NC Series)

MANUAL MOTOR STARTER (MMS) APPLICATIONS

Described below are typical problems encountered in conventional systems, along with the solution offered using the MMS system.

SHORT-CIRCUIT BREAKING PROTECTION

When numerous small and medium motor loads exist in a circuit requiring high breaking capacity, there is no high-breaking capacity circuit breaker with a small rated current for short-circuit protection.

The MMS can be used in 100 kA short-circuit current circuits for three-phase, 240 V motors with rated capacity up to 15 kW, and in 50 kA short-circuit current circuits for three-phase, 415 V motors with rated capacity up to 30 kW.

BACK-UP BREAKING SYSTEM

When a back-up molded case circuit breaker (MCCB) is installed upstream to solve the problem described in "short-circuit breaking protection" above, a short in one of the load circuits also trips the upstream breaker and stops the other operating load circuits.

Despite their compact size, the 32AF and 63AF MMS provide high-performance short-circuit current breaking. They eliminate the need for an upstream circuit breaker for back-up use.

OVERLOAD PROTECTION

Motor protection breakers cannot be adjusted to match the rated current of the motor being protected.

Equipped with a wide-range current adjustment dial (with maximum/ minimum ratio of 1.4 to 1.6), the MMS easily adjusts to match the rated current of the motor, for optimum protection.

CONTROL PANEL SIZE

Considerable space is required to install a back-up circuit breaker or a combination starter consisting of a circuit breaker and a thermal overload relay. As a result, the panel size has to be increased.

The compact size of the MMS, including thermal overload relay functions, enables a smaller installation area with less wiring space, for a reduction in panel size.
