What is a moulded-case circuit breaker (MCCB)?
A moulded-case circuit breaker protects low-voltage circuits against overload and short circuit, with frame sizes typically from about 63 A to 1,600 A. Chinese makers sell thermal-magnetic models for general use and electronic-trip models with adjustable settings for distribution boards and motor control.
What buyers compare
- Frame size and rated current
- Breaking capacity (Icu and Ics in kA)
- Thermal-magnetic or electronic trip unit
- Number of poles and accessories
- Standard: IEC 60947-2
