FAQ

Q: What's the difference between 1-pole and 2-pole breakers?

A: 1-pole breakers handle 120V single circuits (e.g., lights/outlets); 2-pole breakers manage 240V dual circuits (e.g., dryers/water heaters).

Q: What is a 1-pole breaker?

A: A 1-pole breaker protects 120V single-line circuits, controlling power to low-wattage devices like lighting and standard outlets.

Q: Is there a 60 amp single-pole breaker?

A: Rare. 60A breakers are typically 2-pole (240V) for high-power needs; single-pole breakers usually max at 50A for 120V safety.

Q: Is there a 40 amp single-pole breaker?

A: Yes. 40A single-pole breakers exist for 120V high-draw devices like large appliances or specialized equipment.

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?
