## Summary description

CNC residual current breaker with over-current protection model NV821914. Features a 2-pole configuration, 63A rated current, C tripping characteristic, 30mA residual operating current, and 6kA breaking capacity. Designed for electrical distribution systems to provide reliable protection against short circuits, overloads, and earth leakage faults in residential and commercial installations.

## Long description

The CNC NV821914 Residual Current Breaker with Over-Current is an essential electrical safety device designed to provide combined protection against overloads, short circuits, and earth leakage currents in residential and commercial installations. This 2-pole circuit breaker integrates advanced safety features, including an anti-mistake contact terminal block, a flame-retardant housing with high temperature and impact resistance, and a clear contact position indicator showing red for closed and green for opened. It ensures reliable performance in modern electrical distribution systems, protecting both equipment and users from electrical hazards.
Advantages
This residual current breaker offers dependable dual protection, combining overcurrent tripping with residual current detection in a single compact unit. Its robust construction utilizes flame-retardant materials that withstand high temperatures and mechanical impacts for long-term operational durability. The device features a practical contact position indicator for straightforward visual safety checks during maintenance. Additionally, the anti-mistake contact terminal block facilitates secure and reliable wiring, while support for both cable and pin-type busbar connections ensures flexible installation options.
Suitable for
Residential electrical distribution boards and consumer units
Commercial building sub-distribution systems
Protecting individual circuits against overloads and short circuits
Safeguarding users from earth leakage and electric shock risks
This device may not be suitable for industrial environments requiring high-ampere three-phase motor loads or systems operating outside the specified voltage and frequency ratings. It is designed for standard low-voltage installations and should not be used as a primary main breaker where higher breaking capacities exceeding six thousand amperes are required.
