Chint NL210-63-425/30 RCD – 4P – Type B – 63A – 30mA – 10kA
Chint NL210-63-425/30 Type B RCCB with 63A rated current, 30mA sensitivity and 4 pole configuration for advanced residual current protection in three-phase electrical installations.
Why Choose the Chint NL210-63-425/30 Type B Residual Current Device?
The Chint NL210-63-425/30 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 innovative Chint NL210 series, it detects AC, pulsating DC and smooth DC residual currents, making it suitable for circuits where conventional Type AC or Type A RCDs may not provide sufficient protection.
Designed for use in demanding electrical systems, the NL210 continuously monitors residual current and disconnects the supply when a dangerous leakage current is detected. Its Type B residual current protection makes it particularly suitable for installations containing inverters, variable speed drives, EV charging equipment, photovoltaic systems and other power electronic loads.
With a 63A rated current, 30mA residual operating current and 4 pole configuration, the NL210-63-425/30 provides dependable personal protection and advanced residual current detection for three-phase systems requiring robust electrical safety.
Key Advantages
- Advanced Type B residual current protection for modern electrical installations.
- 63A rated current suitable for higher load three-phase circuits.
- 30mA sensitivity provides additional protection against electric shock.
- Detects AC, pulsating DC and smooth DC residual currents.
- Ideal for EV charging, drives, inverters and renewable energy applications.
- Compact DIN rail mounting with dependable Chint engineering.
Key Features

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 where drives, converters, EV chargers and renewable energy systems are present.
The Chint NL210 range provides reliable residual current protection without integrated overcurrent protection, meaning it should be installed alongside a suitable MCB or MCCB. Its fast tripping performance and compact modular design make it suitable for modern electrical distribution systems where safety and reliability are critical.
Typical Applications
- Electric vehicle charging installations.
- Variable speed drives and motor control systems.
- Photovoltaic and renewable energy systems.
- Commercial distribution boards.
- Industrial control panels and switchboards.
- Three-phase installations containing power electronics.
