4P 63A AC MCB

4P 63A AC MCB is an electrical protection device for three-phase four-wire low-voltage power distribution system, mainly used for overload and short circuit protection. It is widely used in industrial, commercial and large residential power distribution systems, and can protect the three-phase live wire and neutral wire at the same time to ensure the safe operation of circuits and equipment.

  • Four-pole protection (4P): cuts off the three-phase live wire and the neutral wire at the same time
  • High current rating (63A): Suitable for circuit protection of high power loads
  • Overload and short circuit protection: can quickly detect overload and short circuit faults
  • High breaking capacity: (usually 6kA or higher)
  • Reliability and durability: Made of high-quality materials
  • Comply with international standards
  • A variety of tripping characteristics are available: B, C, D and other tripping characteristic curves are provided
