CHINT · Residual-current circuit breaker with overcurrent protection
Product overview
CHINT NBH8LE-40 combines residual-current detection with overcurrent protection for AC final circuits. Select the exact current, trip characteristic and residual-current threshold, and distinguish the NBH8LE-40 and -40H breaking-capacity versions.
Technical selection summary
| Listing / reference model | CHINT NBH8LE-40 |
|---|---|
| Product type | Residual-current circuit breaker with overcurrent protection |
| Manufacturer frequency reference | 50/60 Hz AC in the CHINT NBH8LE-40 manufacturer instructions |
| Short-circuit capacity by version | Icn 4.5 kA or 6 kA (H type) in the manufacturer instructions. Match the full NBH8LE-40 / NBH8LE-40H code and actual marking; the 6 kA value does not apply to every version |
The linked 2020.03 instructions cover NBH8LE-40 and NBH8LE-40H. Current rating, residual operating current and breaking capacity are separate selections; match the full model and actual markings. The manual lists AC-type 10/30 mA versions and does not establish every other residual-current option.
Typical applications
- AC final circuits requiring matched residual-current and overcurrent protection.
- Distribution panels with the exact NBH8LE-40 or -40H configuration.
