The GE Limitamp motor control center provides an economical means of centralizing motor starters and related control equipment. It permits motor control starters, feeders, isolator switches, distribution transformers, interlocking relays, programmable control, metering and other miscellaneous devices to be obtained in a single floor-mounted structural assembly fed from a common enclosed main bus.
Limitamp motor control centers are constructed of standardized heavy gauge vertical sections housing vertical and horizontal buses and compartmented starters. Sections are bolted together to form a single line-up assembly. The entire center may be powered by incoming line connection at a single point.
Typical applications are in paper, steel, cement, rubber, mining, petroleum, chemical, and utility-type industries. Limitamp control is also used in water and sewage plants and public buildings for air conditioning, pumps and compressors.

AC Magnetic Motor Controls:
AC controllers for use with new or existing wound rotor or squirrel cage motor drives featuring contactor type secondary control or solid state four quadrant speed regulation. They are ideal for motor primary or secondary controls, eddy current brake hoist, counter torque hoists and life bridge controllers. Also available are adjustable frequency drives. Hubbell AC Motor controllers are designed to meet your specifications and constructed to fit you space.
DC Magnetic Motor Controls:
The most complete line of standard and custom controllers. All controllers are front wired, from connected and front accessible in NEMA rated contactor sizes 0 through 8 for EOT crane control, dynamic lowering and reverse-plugging installations. Also available are mill auxiliary controllers, special circuits to meet custom installation requirements and special construction to meet customer specifications.
AC/DC Solid State Motor Controls:
Hubbell's S²MC Solid State Stepless Motor Controls are ideal for controlling overhauling loads such as lift bridges, bridge cranes, bucket/grapple cranes, portal/whirly cranes, turbine cranes, tramways, and coke oven drives.
Utilizing AC induction motors (squirrel cage and wound rotor) the line of S²MC controllers are available in both primary thyristor (4920 series) and secondary thyristor (4940 series) through 500 hp, or more, and capable of operating on 208/230/380/460/575, 3 phase VAC, 50/60 Hz. The line of S²MC controls have been successfully applied on hundreds of applications for over 15 years.

SINAMICS GL150
The rugged converter for synchronous motors up to 75 MW
The LCI-converter (load commutated inverter) SINAMICS GL150 extends the SINAMICS drive family to highest power ratings.
SINAMICS GL150 is designed as a drive converter for single-motor applications with variable and constant torque characteristic. The converter is available in air- and water-cooled design and achieves power ratings up to 74 MW (water-cooled design). Higher ratings are available on request.
SINAMICS GL150 is used for speed-variable operation as well as for start-up operation of large synchronous motors and generators. The typical speed range extends up to approx. 6000 rpm. When used as start-up converter the speed-range is limited by the synchronous line frequency. Within this range a speed control range of 1:10 or 1:100 can be realized. Due to the topology regenerative (4Q) operation is possible without additional measures. The drive converters SINAMICS GL150 drive converters offer an economical drive solution for highest power ratings of 74 MW and beyond, which can be adapted to specific customer needs with a wide range of optionally available components and accessories.

Spectra Series 8000 Line
Motor control centers provide a convenient, centralized means of protecting and controlling all of a facility's motor loads. In many facilities today, these motor loads often are precision HVAC systems responsible for cooling sensitive electronic equipment - servers, routers, switches, pc's, etc. Any power outage or fault event could severely damage this equipment and ultimately bring all operations to a halt - resulting in huge financial losses.
Since 1940, GE Motor control centers have been designed and manufactured with demanding applications like this in mind. Built using Six Sigma quality guidelines, GE MCCs offer an enormous amount of application flexibility while adhering to the most stringent industry standards.

For the actuation of high frequency surgery devices, foot-operated control devices are applied. The requirements for these control devices are prescribed in EN 60601-1, as well as in EN 60601-2-2. Foot controls for this application field are characterised by defined requirements for the protection class, as well as mechanical stability. Electrostatic charging must be avoided. The requirements for class AP (anaesthesia approved) might also be relevant. In this case the foot controls are gas-proof encapsulated (zone M). The main actuating elements are a yellow pedal (activation »cutting«) and a blue pedal (activation »coagulating«).

Interlock control system
A plug-in modular system for linking up to 10 doors, or up to 10 groups of doors to create an interlock system.
No complicated control system required as dependencies are set on site with DIP-switches at each control module. The system allows for easy expansion.
Quite often one of the requirements of clean-room technology or laboratories is, that certain doors may only be opened ifothers are closed. The DICTATOR interlock control system is the idealsolution to link units of up to 10 doors.
The dependencies between different doors are programmed directly in the
respective control modules on each door using a very easy adjustable matrix control system. This is done with DIP-switches representing the different doors. The dependences / linksnbetween the doors can also be changed on site at a later stage, not requiring any special programming
know-how. The interlock control terminal is provided with a potentialfree make-break contact. This permits e.g. to pass on the information on each door to a central control system.
The DICTATOR interlock control system is a modular system and therefore
extremely flexible and easy to adapt to different sizes of door units and
requirements.

The Euro housing is primarily used for applications that require many joysticks, pushbuttons, toggle switches and other operator interfaces.
Even though while big in size, it is comfortable to wear for the operator, utilizing a shoulder harness.
The Euro is mainly used on applications such as tunnel-drilling-machines and earthmoving equipment.
