## Long description

The Miniature Circuit Breaker CNC NV821440 1-Pole 25A C-Curve 6kA is a dependable electrical protection device engineered to safeguard residential and commercial power distribution systems. This 1-pole miniature circuit breaker is designed to disconnect electrical circuits automatically during overload and short-circuit events, preventing damage to wiring and connected equipment. Constructed with flame-retardant and high-temperature resistant materials, it offers high impact resistance and dependable long-term operation. The device features an anti-mistake contact terminal block and a clear contact position indicator with red for closed and green for opened states.
Advantages
This miniature circuit breaker provides dual protection against both overloads and short circuits to ensure high electrical safety in various environments. Its robust construction utilizes flame-retardant materials with high temperature and impact resistance for enhanced durability. The visual contact position indicator allows for quick and easy status verification. Furthermore, it supports flexible installation options with cable or pin-type busbar connections from either the top or bottom, and mounts easily onto standard DIN rails.
Suitable for
Safeguarding residential electrical installations
Protecting commercial power distribution systems
Overload and short-circuit protection for standard loads
Switchboards and electrical distribution panels
When it may not be suitable
This miniature circuit breaker is not designed for industrial applications requiring breaking capacities above 6kA or operating outside the specified temperature range. It is also unsuitable for direct current applications unless explicitly rated for DC use.
