Why Choose the Chint NL210-63-463/30 Type B Residual Current Device?
The Chint NL210-63-463/30 is a high-performance 4 pole Type B Residual Current Device (RCD/RCCB) designed to provide advanced protection against earth leakage currents in modern commercial, industrial and three-phase electrical installations. As part of the specialist Chint NL210 series, it detects AC, pulsating DC and smooth DC residual currents, making it suitable for circuits containing power electronics and equipment that may generate DC leakage currents.
This RCCB continuously monitors residual current and disconnects the supply when a dangerous leakage fault is detected. Its Type B residual current detection makes it ideal for applications where conventional Type AC or Type A devices may not provide suitable protection, including installations with EV chargers, photovoltaic systems, variable speed drives, UPS equipment and frequency converters.
With a 63A rated current, 30mA residual operating current and 3P+N configuration, the NL210-63-463/30 provides additional personal protection for three-phase systems while delivering reliable performance in demanding electrical distribution environments.
Key Advantages
- Advanced Type B residual current protection for modern electrical systems.
- 63A rated current suitable for commercial and industrial circuits.
- 30mA sensitivity provides additional protection against electric shock.

Advanced Protection for Power Electronic Loads
Type B residual current devices are designed to detect a wider range of leakage currents than standard RCDs, including smooth DC residual currents that may be produced by modern power electronic equipment. This makes them essential for installations using EV chargers, solar inverters, variable speed drives, UPS systems and other converter-based loads.
The Chint NL210 range provides dependable residual current protection without integrated overcurrent protection, meaning it should be installed alongside a suitable MCB or MCCB. Its compact modular design, fast tripping performance and advanced leakage detection make it suitable for demanding three-phase electrical installations.
Typical Applications
- Electric vehicle charging installations.
- Photovoltaic and renewable energy systems.
- Variable speed drives and frequency converters.
- UPS and high-frequency power converter systems.
- Commercial distribution boards.
- Industrial control panels and three-phase switchboards.
