The core difference of CHINT NXBLE-63YH-C20 lies in its combined function of Arc Fault Detection Device (AFDD) + Residual Current Circuit Breaker with Overcurrent Protection (RCBO) (identified by the label YH). It also differs from other models of the same brand in terms of frame current, كسر القدرة, protection type, pole coverage, and function expansion. Below is a structured comparison and model selection guide.

الاختلافات الرئيسية
- YH Exclusive Function: Only the NXBLE-63YH series is equipped with arc fault detection and rapid tripping, which can identify parallel/series arcs and reduce the risk of electrical fires. This function is not available in other models.
- تيار الإطار & كسر القدرة: The NXBLE-63 series has a frame current of 63A and a breaking capacity of 6kA; the NXBLE-32 has a frame current of 32A, and the NXBLE-40 has a breaking capacity of only 4.5kA, making them suitable for different power levels and short-circuit conditions.
- حماية & Pole Coverage: The standard version covers multiple pole configurations (3ف/4ف), ideal for three-phase circuits; the YH/ZB series mainly offers 1P+N/2P configurations, focusing on arc/fault early warning needs for single-phase circuits.
- Differences from the Traditional DZ47LE Series (Upgraded Replacement Relationship)
| عنصر المقارنة | NXBLE-63YH-C20 | DZ47LE-63 C20 | Core Impact |
| سلسلة المنتجات | التالي (KunLun Series; new generation) | DZ47LE (old version; being phased out gradually) | NXBLE boasts superior craftsmanship and protection performance |
| كسر القدرة | 6ال (Class E High Breaking Capacity) | Mainly 4.5kA | NXBLE has stronger resistance to short-circuit impact |
| Function Expansion | Supports AFDD (YH) and self-diagnosis (ZB) | Basic earth leakage protection only | NXBLE meets modern safety requirements |
| أبعاد التثبيت | 1P+N=36mm, 2P=72mm | Same dimensions; direct replacement available | No cabinet modification needed for upgrading |
ثالثا. Model Selection Decision Tree (Rapid Demand Matching)
- If arc fire protection is required (على سبيل المثال, old wiring, flammable locations) → choose the NXBLE-63YH series (على سبيل المثال, C20).
- If only regular earth leakage/overload/short-circuit protection is needed → choose NXBLE-63 (63A high current) or NXBLE-32 (≤32A low current).
- If audible and visual fault alarm is required (unattended scenarios) → choose the NXBLE-63ZB self-diagnostic series.
- For three-phase circuits (380V) → prioritize the NXBLE-63 standard version (3P/3P+N/4P); the YH/ZB series are mostly single-phase.
- Installation and Replacement Precautions
- Pole Matching: لنماذج 1P+N, strict distinction must be made between live (ل) and neutral (ن) الأسلاك; الاتصال العكسي محظور. The YH series mainly offers 1P+N/2P configurations, and other models should be selected for three-phase circuits.
- منحنى التعثر: All models adopt C-type curves (5~10In), suitable for lighting and general power loads; for impact loads such as motors, D-type tripping models are recommended.
- نوع التسرب: The YH series is mainly Type AC, with some models supporting Type A (compatible with pulsating DC leakage). Confirm the load leakage type before replacement.
- Dimension Compatibility: NXBLE and DZ47LE share the same installation dimensions, allowing direct replacement without modifying the distribution cabinet layout.
