## Summary description

CNC miniature circuit breaker model NV821570 designed for electrical circuit protection. This 3-pole device features a 50A rated current, C tripping curve, and a 6kA breaking capacity. Ideal for safeguarding commercial and residential electrical installations against overloads and short circuits, ensuring reliable power distribution and safety.

## Long description

The CNC NV821570 Miniature Circuit Breaker 3-Pole 50A C-Curve 6kA is a reliable electrical protection device designed to safeguard commercial and residential installations against overloads and short circuits. This three-pole modular circuit breaker ensures safe power distribution and effective control in modern electrical systems. Built with quality materials, it features anti-mistake contact terminal blocks, flame retardant housing with high temperature and impact resistance, and clear contact position indication showing red for closed and green for opened.
Advantages
This miniature circuit breaker provides robust dual protection against both overcurrent overloads and short circuits. The device incorporates a flame-retardant exterior that resists high temperatures and physical impacts for enhanced operational durability. Anti-mistake contact terminal blocks improve installation safety, while the visual contact position indicator allows for quick status checks. With a mechanical lifespan of up to 20,000 cycles and an electrical lifespan of 8,000 cycles, it delivers long-term reliable performance in electrical distribution boards.
Suitable for
Safeguarding residential electrical distribution boards
Protecting commercial building power circuits
Managing three-phase electrical loads requiring a 50A rated current
Installations on standard 35mm DIN rails
When it may not be suitable
This circuit breaker is not designed for main incoming grid isolation requiring high current ratings beyond 50A, nor is it suitable for direct outdoor exposure without a proper weatherproof enclosure due to its IP20 safety class. It should not be used in high-temperature environments exceeding the specified operating limit of plus 40 degrees Celsius.

How to use
The device is designed for professional installation on a standard 35mm DIN rail using the integrated fast clip device. Connections can be made from either the top or the bottom using cables or pin-type busbars with a cross-sectional area of up to 25mm² or 18 to 3 AWG. Ensure that the system power is completely disconnected before mounting, wiring, or servicing the circuit breaker. Verify all terminal connections are securely tightened to prevent loose contact issues during operation.
What to consider before purchase
Verify that the 50A current rating and C-curve match your specific load requirements
Check that your electrical distribution board has sufficient DIN rail space for the 54mm width
Ensure operating ambient temperatures remain within the minus 5 to plus 40 degrees Celsius range
Usage recommendations
Always have electrical installations and circuit breaker mounting performed by a qualified electrician in compliance with local electrical codes and standards. Periodically check terminal connections and test the mechanical operation to maintain optimal safety and performance.
