## Long description

The Miniature Circuit Breaker CNC NV821464 1-Pole 40A C-Curve 6kA is designed for reliable electrical circuit protection against overloads and short circuits. This 1-pole device features a 40A rated current, C-curve tripping characteristic, and a 6kA breaking capacity. Ideal for residential and commercial electrical installations, this circuit breaker ensures safety and compliance with modern standards. It is equipped with an anti-mistake contact terminal block, flame retardant housing with high temperature and impact resistance, and a clear contact position indication showing red for closed and green for opened.
Advantages
This miniature circuit breaker provides robust protection against both electrical overloads and short circuits to safeguard electrical systems and connected equipment. The housing is manufactured from flame-retardant materials offering high temperature and impact resistance for enhanced durability and safety. An anti-mistake contact terminal block prevents wiring errors during installation. Users benefit from immediate visual feedback regarding the operational state via the distinct red and green contact position indicators. The unit supports flexible connection options from both top and bottom using cables or pin-type busbars, and mounts efficiently onto standard 35mm DIN rails.
Suitable for
Residential electrical distribution boards
Commercial building sub-circuits
Protection of lighting and power circuits requiring a 40A current rating
Installations on standard 35mm DIN rails EN 60715
When it may not be suitable
This device is not designed for industrial environments requiring breaking capacities exceeding 6kA or operating outside the specified temperature range of -5°C to +40°C. It is also unsuitable for direct current systems since it is rated for AC 230/400 V electrical networks.

How to use
The circuit breaker should be installed within a suitable enclosure on a standard 35mm DIN rail using the integrated fast clip device. Ensure the power supply is disconnected before performing any wiring work. Connect the incoming and outgoing conductors to the top or bottom terminals, making sure the cross-sectional area does not exceed 25mm² and that the screws are securely tightened to maintain proper electrical contact. Verify the correct positioning of cables in the anti-mistake terminals. Once installed, test the switching mechanism manually to ensure smooth operation, observing the red and green contact position indicators.
What to consider before purchase
Verify that the 40A rated current and C-curve match your specific load requirements
Confirm that the available system voltage corresponds to AC 230/400 V
Ensure the installation environment stays within the -5°C to +40°C operating temperature range
Check that your distribution board has a standard 35mm DIN rail and sufficient physical space of 18 mm width per pole
Usage recommendations
Always ensure that electrical installations are performed by a qualified professional in accordance with local regulations and standards such as IEC 60898-1. Periodically inspect the device for physical damage and verify terminal tightness to maintain safe, long-term operation.
