Differences between c60n and 120n breakers

C60N and C120N are both types of molded case circuit breakers (MCCBs) manufactured by Schneider Electric, a leading global provider of electrical distribution and automation solutions. While they share some similarities, there are key differences between the two:

1. Current Rating:

• C60N: Rated for 60A continuous current
• C120N: Rated for 120A continuous current

2. Voltage Rating:

• Both C60N and C120N are designed for 3-phase, 4-wire systems and are rated for 690V AC (690V peak) or 480V AC (480V peak) nominal voltage.

3. Frame Size:

• C60N: Has a smaller frame size, making it more suitable for smaller applications
• C120N: Has a larger frame size, making it more suitable for larger applications

4. Thermal Current (Ith):

• C60N: Has a thermal current rating of 40A
• C120N: Has a thermal current rating of 80A

5. Short-Circuit Current Rating (Ics):

• C60N: Has a short-circuit current rating of 30kA
• C120N: Has a short-circuit current rating of 40kA

6. Interrupting Rating:

• C60N: Has an interrupting rating of 30kA
• C120N: Has an interrupting rating of 40kA

7. Coil Voltage:

• C60N: Typically requires a 24V DC coil voltage
• C120N: Typically requires a 24V DC coil voltage or 120V AC coil voltage (depending on the specific model)

8. Applications:

• C60N: Suitable for smaller applications, such as residential, commercial, and industrial settings
• C120N: Suitable for larger applications, such as industrial, commercial, and utility settings

In summary, the main differences between C60N and C120N breakers are their current rating, frame size, thermal current rating, short-circuit current rating, and interrupting rating. The C120N breaker is designed for larger applications and has a higher current rating, while the C60N breaker is suitable for smaller applications.
