## Summary description

The CNC NV821884 residual current breaker with over-current protection is designed to ensure electrical safety in residential and commercial circuits. This 2-pole device operates at 20A with a C tripping curve, features a 30mA residual operating current, and has a 6kA breaking capacity. It provides reliable protection against short circuits, overloads, and earth leakage faults, making it suitable for safeguarding wiring installations and preventing electric shock in modern electrical distribution systems.

## Long description

The CNC NV821884 residual current breaker with over-current protection is engineered to deliver reliable electrical safety across residential and commercial circuits. This 2-pole device combines overload protection, short-circuit protection, and earth leakage detection into a single unit. Designed for modern electrical distribution systems, it helps safeguard wiring installations and protects users against electric shock hazards. Built with a flame-retardant housing that offers high temperature and impact resistance, the unit features an anti-mistake contact terminal block and a clear contact position indicator displaying red for closed and green for open.
Advantages
This residual current circuit breaker provides comprehensive circuit protection by integrating multiple safety functions into a compact housing. The mechanical design includes high temperature and impact resistance along with a flame-retardant exterior for enhanced durability in demanding environments. Installation is streamlined through standard DIN rail mounting and flexible connection options supporting both cables and pin-type busbars up to 35mm². Clear visual indicators allow for immediate verification of contact status, while the robust internal mechanism ensures a long operational lifespan under regular electrical loads.
Suitable for
Safeguarding residential electrical distribution boards and consumer units
Protecting commercial building wiring and lighting circuits
Preventing electric shock from direct and indirect contact in indoor installations
Guarding against equipment damage caused by electrical overloads and short circuits
When it may not be suitable
This device is not designed for industrial applications requiring higher breaking capacities exceeding 6kA or continuous operating currents above 20A. It is also unsuitable for direct outdoor exposure without a properly rated weatherproof enclosure, as it holds an IP20 safety class.

How to use
The device must be installed by a qualified electrician in accordance with local electrical regulations and applicable safety standards. Mount the unit onto a standard 35mm DIN rail inside a suitable distribution enclosure. Connect the incoming supply wires from the top terminals using appropriately sized cables or a pin-type busbar up to 35mm², ensuring all terminal screws are securely tightened to prevent loose connections. Periodically test the residual current functionality using the integrated test button to verify proper mechanical and electrical operation.
What to consider before purchase
Verify that the 20A rated current matches the electrical load requirements of your specific circuit
Ensure the 30mA residual sensitivity aligns with standard personal protection needs
Check that your distribution board has sufficient space on a 35mm DIN rail, noting the unit dimensions of 82 x 36 x 78 mm
Confirm compatibility with top-side cable entry or pin-type busbar connections
Usage recommendations
Always disconnect the main power supply before performing any installation, maintenance, or inspection work on the electrical panel. Regularly inspect the enclosure and test the breaker functionality to maintain optimal safety performance over time.
