The Chint NBP125-2P/80A is a type of قاطع الدائرة manufactured by Chint Electric.
تفسير النموذج: “شينت” is the English brand name of Chint Group. في “NBP125”, “NBP” is likely the series code for Chint’s specific circuit breaker line; “125” indicates the rated frame current is 125A, meaning the maximum current the breaker’s frame can withstand stably is 125A. “2ص” stands for 2 أقطاب, والتي يمكنها التحكم في كل من السلك الحي والسلك المحايد في وقت واحد. “80أ” refers to the rated current of 80A, representing the maximum current the circuit breaker can carry safely and stably for a long period.
الميزات الوظيفية: This model is an external circuit breaker for electricity meters. It is suitable for AC 50Hz circuits with a rated voltage of 230V, توفير حماية الزائد وماس كهربائى. في أثناء, as a supporting circuit breaker for smart electricity meters, it is equipped with functions of remote control tripping and automatic closing after fee recharge.
المعلمات التقنية: It complies with standards such as GB/T 10963.1 and CQC 1121. The pollution degree is Class 2, the protection class is IP20, the installation category is Class II and III, and the ambient air temperature range is -25°C ~ +60°C.
Appearance and Installation: It generally adopts a plastic case structure, featuring small size, light weight and easy installation. It is usually installed on a DIN rail and can be conveniently mounted inside a distribution box.

Key Points for Alternative Model Selection
- Functional Matching: Select external circuit breakers for electricity meters that must have the three core functions: remote control tripping, automatic closing after fee recharge—these are the core features of the NBP series.
- Parameter Consistency:
البولنديين: strictly 2P (controlling both live wire and neutral wire at the same time)
التصنيف الحالي: 80أ (long-term operating current)
Frame current rating: ≥ 80A (125A is recommended, consistent with the original model)
الجهد المقنن: AC 230V (for single-phase fee control applications)
- Certification Compliance:
Must have CCC Compulsory Certification and CQC Certification
Comply with the State Grid Technical Specification for External Circuit Breakers of Electricity Meters (Q/GDW 11421-2015)
Pollution degree Class 2, protection class IP20, installation category Class II/III
- Installation Compatibility:
Standard 35mm DIN rail mounting (consistent with the NBP series)
Width is recommended to be ≤ 36mm (to ensure space compatibility inside the distribution box)
- Communication Compatibility:
For network management, select models supporting RS485 communication or power line carrier communication
Communication protocols must be compatible with the State Grid/Southern Power Grid power consumption information collection system
Recommendation Priority
- Chint same-series alternatives (NBP-125NZS/2P 80A): Fully compatible, no need to adjust any wiring or settings
- Other Chint series (NXB-125(G)/2P 80A): Same brand, reliable quality, convenient installation and maintenance
- Other brands’ State Grid standard models (SCB8ZY-125M/2P 80A): Potentially more cost-effective with fully matching functions
