Motor Control Centers (7700 parts, 8000 and 9000 Series)
GE Motor Control Centers offer an ideal means of quickly providing centralized motor control and other related control equipment. A pre-engineered version of the GE motor control center is available at short-cycle and mid-cycle shipment. The product scope available is more limited than with normal cycle shipments, and includes certain combination starter units, feeder units, distribution transformers, lighting panels, relaying panels, programmable controllers and other miscellaneous devices to be installed in a single, floor-mounted enclosure and fed from a common enclosed horizontal and vertical bus system.
Each GE motor control center vertical section is constructed of 0.090-inch (13-gauge) steel which is subjected to a special corrosion- resistant zinc-phosphate treatment followed by a powder paint process using ANSI-61 light gray alkyd-enamel paint. Each section houses the horizontal and vertical bus; horizontal and vertical wire ways and the compartmentalized individual control units. Standard unit construction is Class I Type B wiring1. Factory assembled, wired and tested units are mounted in each vertical section, and sections are easily bolted together to form a motor control center line-up. The entire line-up is then powered by a single incoming-line connection. Standard UL labeled NEMA 1 enclosure contains 600-ampere, three-phase, copper tin-plated horizontal main bus, 300-ampere, three-phase, copper tin-plated vertical bus and is braced to withstand a fault current of 65,000 rms symmetrical. Each vertical section must be priced to include 72 inches of vertical space units consisting of starters, feeders, transformers, panels, incoming terminal boards and/or enclosure spaces for future units.
A wide array of renewal parts are available from the PartsSuperCenter, including O/L Resets, transformers, filler kits, blank doors and hinges.
