## Long description

The Miniature Circuit Breaker CNC NV821532 3-Pole 20A C-Curve 6kA is a dependable three-pole electrical protection device engineered to safeguard electrical distribution systems from overloads and short circuits. Manufactured by CNC, this miniature circuit breaker features a 20A rated current, a C-curve tripping characteristic suitable for moderate inrush current loads, and a 6kA breaking capacity. Built with safety and durability in mind, it incorporates flame-retardant, high-temperature, and impact-resistant housing, alongside a clear contact position indicator showing red for closed and green for opened states.
Advantages
This circuit breaker ensures reliable circuit protection with anti-mistake contact terminal blocks that facilitate secure and correct wiring. The durable construction offers high mechanical and electrical endurance, capable of up to 20,000 mechanical cycles and 8,000 electrical cycles. Versatile installation options allow connection from both the top and bottom using cables or pin-type busbars, while the fast clip device enables mounting on standard 35mm DIN rails.
Suitable for
Residential electrical distribution boards
Commercial building sub-circuits
Light industrial automation panels
Overload and short-circuit protection for 400V AC systems
When it may not be suitable
This device is not designed for main incoming power supplies requiring higher breaking capacities exceeding 6kA. It is also unsuitable for high-inrush current inductive loads that require a D-curve characteristic or environments operating outside the specified temperature range of -5°C to +40°C.
Key specifications
3 poles
Rated current: 20 A
Trip characteristic class: C
Rated voltage: 400 V AC
Rated breaking capacity: 6000 A
Terminal cross-sectional area: up to 25 mm²
Safety class: IP20
Standard compliance: IEC 60898-1 / EN 60898-1
How to use
Mount the miniature circuit breaker securely onto a standard 35mm DIN rail using the fast clip device inside a compatible distribution enclosure. Connect the incoming and outgoing power supply lines to the top or bottom terminals, ensuring the wire cross-sectional area does not exceed 25 mm² and terminal screws are properly tightened. Test the mechanical operation and verify the contact position indicator before energizing the system.
What to consider before purchase
Verify that the 20A rated current and C-curve match your specific load requirements.
Check that your electrical system voltage does not exceed the rated 400V AC.
Ensure compatibility with standard 35mm DIN rail mounting and available enclosure space.
Usage recommendations
Always ensure that electrical installation and maintenance are performed by a qualified electrician in accordance with local safety regulations and standards. Regularly inspect the device for mechanical wear and test the functionality of the breaker to maintain optimal system safety.
