## Long description

The Miniature Circuit Breaker CNC NV821457 1-Pole 32A C-Curve 6kA is a reliable electrical protection device manufactured by CNC. Designed to safeguard residential and commercial electrical installations, this miniature circuit breaker effectively protects circuits against overloads and short circuits. It combines robust safety features, including an anti-mistake contact terminal block, flame retardant construction with high temperature and impact resistance, and a clear contact position indicator showing red for closed and green for opened.
Advantages
This miniature circuit breaker offers dependable performance for electrical systems requiring precise overload and short-circuit protection. Its durable housing features flame retardant and high temperature resistant materials to ensure longevity and safety during operation. The device is engineered with an anti-mistake contact terminal block and features a visible contact position indicator for straightforward operational status checks. Furthermore, it supports flexible installation methods, accommodating connections from both top and bottom using cables or pin-type busbars.
Suitable for
Protecting residential electrical installations against overloads and short circuits
Safeguarding commercial building electrical circuits and distribution boards
Applications requiring a 1-pole 32A capacity with a C tripping curve
Standard DIN rail mounting in electrical control panels
When it may not be suitable
This device is not designed for environments operating outside its specified temperature range of -5°C to +40°C or in areas requiring multi-pole switching beyond a single pole. It is also unsuitable for high-current industrial applications that exceed a 32A rated current or a 6kA breaking capacity.
