CHINT · Residual current circuit breaker
Product overview
The CHINT NL1-63 provides residual-current protection without integral overload or short-circuit protection. This listing covers 2P construction and type ac or type a selection; match the complete manufacturer order code.
Technical selection summary
| Manufacturer model | NL1-63; select the complete current, pole, waveform and sensitivity code |
|---|---|
| Rated current on this page | 25, 40 or 63 A |
| Pole construction | 2P in the manufacturer order table; confirm phase and neutral terminal markings |
| Voltage / frequency | 2P: AC 230/240 V; 4P: AC 400/415 V, 50/60 Hz |
| Residual-current type | Type AC or Type A; Type A includes pulsating DC detection, while Type AC covers sinusoidal AC |
| Sensitivity | 30, 100 or 300 mA; select the actual protection and selectivity requirement |
| Conditional short-circuit duty | Use the exact 6/10 kA conditional Inc / IΔc version with its specified upstream SCPD; this is not independent overcurrent protection |
| Manufacturer reference | IEC/EN 61008-1; 35 mm DIN-rail mounting |
Use the manufacturer 2P/4P construction rather than interpreting phase-plus-neutral wording as a different fuse or breaker model. Match detection type, instantaneous or timed release, sensitivity and upstream protection separately. Destination approvals must match the supplied version.
Typical applications
- Distribution and control assemblies matched to the specified device
- Replacement procurement using the complete CHINT model
