The CHINT NXBLE-63 1P+N Residual Current Circuit Breaker (RCBO) is designed to provide combined electrical protection against earth leakage, overload and short-circuit faults in single-phase AC electrical installations.
By combining the functions of an MCB and residual current protection in one compact device, the NXBLE-63 helps protect electrical circuits, equipment and people against electrical faults.
The 1P+N configuration provides phase protection with a neutral pole. CHINT’s certification documentation identifies the neutral pole in the 1P+N configuration as uninterrupted.
With rated current options from 6A to 63A, multiple residual operating current options and B, C and D tripping characteristics, the NXBLE-63 is suitable for a range of residential, commercial and industrial distribution applications.
Its compact DIN rail mounting design makes it suitable for installation in electrical distribution boards and control panels.

The RCBO detects residual current caused by leakage to earth and disconnects the circuit when the applicable operating threshold is reached.
This function helps reduce the risk of electric shock and electrical fire associated with earth leakage faults.
Thermal protection responds to excessive current flowing through the circuit over time, helping protect cables and connected electrical equipment from overload damage.
Magnetic protection operates during short-circuit faults and disconnects the circuit to help limit damage to electrical installations.
The NXBLE-63 combines three protection functions in one compact device:
| Current Rating | Product Configuration |
|---|---|
| 6A | 1P+N RCBO |
| 10A | 1P+N RCBO |
| 16A | 1P+N RCBO |

Availability of individual ratings is subject to stock confirmation.
| Curve | General Application |
|---|---|
| B Curve | Resistive and low-inrush-current circuits |
| C Curve | General electrical and commercial loads |
| D Curve | Loads with high starting or inrush current |
Select the correct curve according to the connected load, cable characteristics and prospective fault current.
| Sensitivity | Typical Selection Consideration |
|---|---|
| 30mA | Additional protection against electric shock |
| 50mA | Application-specific residual current protection |
| 75mA | Application-specific residual current protection |
| 100mA | Leakage protection and installation coordination |
| 300mA | Higher-threshold leakage and fire-protection applications |
The appropriate sensitivity must be selected according to the electrical installation design and applicable regulations.
The CHINT NXBLE-63 1P+N RCBO can be used in:
Important: An RCBO does not replace the protective earthing system. Correct earthing, wiring and circuit coordination are essential for safe operation.
Q1. What is CHINT NXBLE-63 RCBO?
The CHINT NXBLE-63 is a residual current circuit breaker with integrated overload and short-circuit protection.
Q2. What does 1P+N mean?
1P+N means one protected phase pole and one neutral pole. CHINT’s certification documentation identifies the neutral pole as uninterrupted.
Q3. What protection does the NXBLE-63 provide?
It provides earth leakage, overload and short-circuit protection.
Q4. What current ratings are available?
The product series includes 6A, 10A, 16A, 20A, 25A, 32A, 40A, 50A and 63A ratings.
Q5. What is the breaking capacity?
CHINT’s product documentation specifies a 6kA short-circuit breaking capacity.
Q6. What residual current sensitivities are available?
The documented series options include 30mA, 50mA, 75mA, 100mA and 300mA.
Q7. What is the difference between an MCB and an RCBO?
An MCB provides overload and short-circuit protection, whereas an RCBO combines these functions with residual current (earth leakage) protection.
Q8. Can an NXBLE-63 RCBO be used in a single-phase distribution board?
Yes. The 1P+N configuration is intended for suitable single-phase AC applications.
Q9. Does the RCBO protect against electric shock?
Its residual current protection provides additional protection against certain electric shock hazards. It does not eliminate all electric shock risks or replace proper earthing and safe electrical practices.
