الأسئلة الشائعة
أسئلة شائعة
What does a compressor pressure switch do?
It closes at a low cut-in pressure to start the compressor and opens at the high cut-out pressure to stop it.
Why include an overload contact?
It opens the control circuit if the motor overload trips, preventing the contactor from remaining energized.
Is this the motor power circuit?
No. It is the low-voltage control circuit; the motor power wiring is shown separately.
