Whether your application is for an AC or DC circuit,
for single-phase power or three-phase power or a sensor
feed-through, the basic hermetic terminal design your
need is determined by the voltage and the current involved:
|
|
Higher voltages require
greater insulation spacings between conductor pins
and ground, and thus a larger terminal size. Minimum
insulation distances are defined by UL for various
voltage and volt-amp ranges. |
|
|
|
|
|
Higher maximum continuous
current (MCC) ratings require larger diameter conductor
pins or the addition of a copper core to the pin in
order to maintain acceptable pin temperatures during
motor-compressor operation |
The following list shows the typical Voltage and Current
ranges for various ACR compressor applications. Click
on the associated button in the "electrical characteristics"
column to see design details and currently available models
for the hermetic terminal family. Or you may go to the
chart at the bottom of this page, find you specific Voltage
and MCC ratings, and click on the appropriate portion
of the chart.
