Refrigeration & Air Conditioning Technology
OBJECTIVES After studying this unit, you should be able to • describe the
differences between a relay, a contactor, and a starter. • state how the locked-
rotor current of a motor affects the choice of a motor starter. • list the basic
components of a ...

Commercial Refrigeration for Air Conditioning Technicians
The thermostat, high-pressure, and low-pressure controls are wired in series with
the contactor coil. To stop a 30 motor, all three power wires must be opened at
the same time. Single-phase compressors only need one of the two power legs ...

Oilfield Processing of Petroleum: Natural gas
It should be located as close as possible to the amine contactor. It can be
complemented, but not replaced, by an integral scrubber in the contact tower.
Removal of contaminants from the inlet gas is enhanced by washing the gas with
water.

Handbook of Electric Motors
When the start button is pressed, contactor M picks up, latching itself in by means
of auxiliary contacts M,, and connecting the motor circuit to the line by main
contacts M. Contactor 1A is the accelerating contactor. At start, the only voltage ...

Once he determined that line voltage was being supplied to the unit, the next
logical step was to check for low voltage; but, William first checked to make
certain that voltage was present on the line side of the cooling contactor. This is
not ...

Industrial Motor Control
The field contactor looks very similar to a common three—pole contactor (Figure
45-5). This is not a standard contactor, however. The field contactor contains a
DC coil and is energized by the excita— tion current of the rotor. The field
contactor ...

Commercial Electrical Wiring
An auxiliary contactor (C4) is connected in series with the stop pushbutton and in
parallel with the start pushbutton. The control circuit also has normally closed
overload contactors (OC) connected in series with the magnetic starter coil (C).

Standard Handbook of Petroleum & Natural Gas Engineering
The wet gas leaves the top of the inlet scrubber and passes to the vertical glycol-
gas contactor. The gas enters the bottom of this vessel and flows upward through
the contact medium countercurrent to the glycol flow. The contact medium in the ...

Practical Variable Speed Drives and Power Electronics
In addition, closing the motor side contactor when converter output voltage is
present can result in a motor inrush current similar to DOL starting. Apart from the
stress this places on the converter, the drive will trip on over-current. Repeated ...
