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
- Suitable for AC systems
