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.

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.

Marechal Electric manufactures a comprehensive range of both industrial and hazardous-area electrical connectors from 5 to 700A. However given the pressure on costs faced by industry, we are promoting in particular a new concept for our Decontactor sockets. The decontactor has been traditionally used as a general supply socket outlet in various industries up to 250A.
However the decontactor is also switch-rated and thus safe to make and break on load and provide visible isolation. As such a mechanic can disconnect and isolate a motor in seconds without incurring the costs of an electrician. Downtime is reduced with lower labour costs.
With companies looking for every advantage and a relentless drive to reduce costs the decontactor could be the newest concept to help them in pursuit of operating efficiency. Whether it’s a failed motor holding up production, a conveyor that needs to be re-positioned, a mixing vessel for wash down or a fan requiring maintenance there is a decontactor to suit the job offering IP66/67, no access to live parts and proven electrical performance.
We constantly meet plant engineers steeped in the tradition of hard-wiring who then, when presented with the decontactor concept, immediately grasp what a motor connected with a decontactor means in terms of time-saving, cost-saving and enhanced safety.
