FAQ
How does an AC contactor work?
An AC contactor uses an electromagnetic coil to open/close electrical contacts: when energized, the coil creates a magnetic field that pulls contacts closed to conduct current; de-energization releases the coil, and springs return contacts to open.
How to tell if contactor is AC or DC?
Check the coil label: AC contactors are marked "AC" or include frequency (50/60Hz); DC contactors are labeled "DC" and lack the AC coil’s shading ring.
Why use a contactor instead of a switch?
Contactors handle higher currents (up to hundreds of amps), support remote control, and endure frequent operation—ideal for motors/heavy loads—unlike switches, which are manual and limited by current capacity.
What happens when an AC contactor goes bad?
Common issues: stuck contacts (circuit won’t open), failed coil (no power), or overheating. This causes equipment failure, overloads, or fire risk if unaddressed.
What does a contactor do in HVAC?
In HVAC systems, contactors control power to compressors, fans, and pumps, switching loads on/off based on thermostat signals to regulate temperature and airflow.
What certifications do your contactors have?
Our contactors comply with international safety standards and mainstream certifications for global markets.
Do you support OEM/ODM services?
Yes, we offer OEM/ODM customization for contactors, including branding, specifications, and design tailored to client needs.
What is the lead time for contactor orders?
Lead time varies by region and order volume; contact our team for a detailed quote based on your location.
