The CHINT NL1-63 2 Pole Residual Current Circuit Breaker (RCCB) is designed to detect earth leakage faults and disconnect the electrical supply when residual current exceeds its specified sensitivity. It provides additional protection against electric shock and helps reduce fire risks associated with electrical leakage faults.
Suitable for single-phase electrical distribution systems, this RCCB is available in different rated-current and residual-current sensitivity configurations, including 30mA and 300mA options, depending on the exact model.
Important: The NL1-63 is an RCCB, not an RCBO. It provides residual-current protection only and does not provide built-in overload or short-circuit protection. Install a suitable MCB or fuse for overcurrent protection.

Model selection note: The 30mA and 300mA sensitivities are separate product configurations, not selectable settings on one device. Rated current, residual-current type, and exact order code must be confirmed before ordering.
| Sensitivity | Typical Application |
|---|---|
| 30mA | Additional protection against electric shock, where required by the installation design and applicable regulations. |
| 300mA | Installation-level leakage protection and reduction of fire risks associated with insulation faults. |
Selection guidance: A 300mA RCCB should not be treated as equivalent to 30mA additional protection against electric shock. Select sensitivity according to the installation design, earthing arrangement and applicable electrical regulations.
| Type | Detection Capability |
|---|---|
| Type AC | Detects sinusoidal alternating residual current. |
| Type A | Detects sinusoidal AC and pulsating DC residual current. |
Always verify the exact residual-current type printed on the device and stated in its model code before purchase.
1. What is the CHINT NL1-63 2 Pole RCCB used for?
It detects residual current caused by earth leakage and disconnects the circuit when the specified operating threshold is reached.
2. Does the NL1-63 provide overload protection?
No. It is an RCCB without built-in overload or short-circuit protection. A suitable MCB or fuse is required.
3. What is the difference between 30mA and 300mA?
30mA is commonly used for additional protection against electric shock. 300mA is generally used for installation-level leakage and fire-risk protection. The correct selection depends on the electrical installation.
4. Is the NL1-63 suitable for single-phase systems?
Yes. The 2P version is designed for compatible single-phase applications.
5. Is the NL1-63 an RCBO?
No. The NL1-63 is an RCCB. An RCBO combines residual-current protection with overload and short-circuit protection.
6. Does CHINT offer Type A and Type AC versions?
Yes. The NL1 product range includes Type A and Type AC configurations. Availability depends on the exact model and order code.
7. What voltage is the 2 Pole NL1-63 designed for?
The CHINT catalogue lists AC 230/240V for the 2P configurations.
