FAQ

What are the advantages of NO contactors?

Normally Open contactors are widely used because they only carry current when activated, which makes them energy-efficient and safer for variable loads. They are ideal for HVAC compressors, pumps, and lighting systems where switching is required.

What does NO and NC mean in contactors?

In contactors, NO (Normally Open) means the circuit is open until the coil is energized, allowing current to flow only when activated. NC (Normally Closed) means the circuit stays closed by default and opens when the coil is energized. These functions are essential for controlling different types of electrical loads.

Where are NO, NC, and 2NO/2NC contactors used?
  • Normally Open contactors are commonly used for variable loads such as motors, HVAC systems, and lighting.

  • Normally Closed contactors are used for fixed or safety-critical loads, ensuring continuity until intentionally deactivated.

  • 2NO/2NC contactors combine both options in one device, making them ideal for automation systems and complex industrial applications.


At Contactor Depot, we carry all these configurations (NO, NC, and 2NO/2NC contactors) in multiple pole and voltage options to match your application.

What is the difference between NO, NC, and 2NO/2NC contactors?

The difference lies in how the contacts behave:

  • NO contactors start open and close when energized.
  • NC contactors start closed and open when energized.
  • 2NO/2NC contactors provide a mix of both, offering greater flexibility for dual operations in HVAC, motor control, and automation.
