As electrical systems evolve toward smarter and more demanding environments, CNC Electric continues to push the boundaries of safety and reliability. The newly developed YCB3RL-63 RCCB builds upon our proven YCB3 series platform, offering a more sensitive, robust, and efficient protection solution for modern power distribution systems.
With the growing complexity of residential and commercial electrical networks—especially the increasing use of electronic loads and variable frequency equipment—traditional RCCBs often face challenges in detecting pulsating DC residual currents.
The YCB3RL-63 was developed by CNC’s R&D team to meet this need, ensuring stable performance even under mixed current and fluctuating voltage conditions, without requiring external power.
Rated current (In): 6–63 A
Poles: 1P+N / 3P+N
Rated residual operating current (IΔn): 10 / 30 / 100 / 300 mA
Type: A / AC
Type A detection: identifies both AC and pulsating DC leakage, outperforming standard Type AC RCCBs on the market
Electromagnetic tripping mechanism: ensures reliable action even during power instability, a key safety advantage for critical environments
Optimized mechanical structure: improves tripping speed and service life, verified through extensive endurance testing
Compact and modular design: simplifies installation and supports flexible panel configurations
YCB3RL-63 represents CNC Electric’s next step toward comprehensive electrical protection, bridging high safety performance with practical usability. Designed for residential, commercial, and light industrial sectors, it empowers contractors, installers, and users with confidence that every connection is protected by CNC’s commitment to safety and innovation.
