Medium Voltage Panels

Medium Voltage Panels

Medium voltage starter family provides flexibility never before available. Rated at 2200– 15,000 volts up to 8000 hp, they are the first starters designed as integrated, complete units precisely matched to motor ratings, and engineered to provide component-to-component circuitry and front accessibility of all components and terminals. TIM starters are used in a variety of industrial process applications, such as pulp and paper, petrochemical, HVAC (chillers), where proper control and protection of the motor and system are critical to the user TIM has been the most one industry in medium voltage motor control for 2 years in these applications, and our starters have been designed with that experience behind them.

Application Description

TIM starters are equipped with current limiting power fuses to interrupt the short-circuit faults shown below. The contactor and fuses are completely coordinated.
Squirrel Cage Motor Motor Starters:

motors are available in full or reduced voltage designs in all ratings. Full voltage starters are available one-high or twohigh in a factory-assembled structure. Electromechanical reduced voltage starters are available in either reactor or autotransformer type. Both provide closed transition from reduced to full voltage. See table on page 6 for application data.
Features, Benefits and Functions Personnel Safety:

A positive mechanical isolating switch with visible disconnect completely grounds and isolates the starter from the line connectors with a mechanically driven isolating shutter, leaving no exposed high voltage.

Additionalsafety features include:

● Isolated cable entry for added safety. The starters and cables are completely isolated from each other by steel barriers
● All new low voltage wireway. Low voltage wire is isolated from the medium voltage compartment, and customer terminal blocks are accessible through the low voltage control panel
● Easily accessible low voltage panel completely isolated from the medium voltage compartment that offers generous device mounting space
● Standard viewing window for visual verification of isolation switch operation
● Optional remote operator for isolation switch allows user to open and close switch while remaining outside the equipment flash boundary
