## Long description

Miniature Circuit Breaker HiSmart NV821464 1P 40A Class C is a single-pole protection device rated for 40 A with a C tripping characteristic. It is designed to protect residential and light commercial circuits from overloads and short circuits, and is intended for DIN-rail (35 mm EN 60715) installation in distribution boards. The breaker features a clear contact position indicator and is suitable for use with cable or pin-type busbar connections.
Advantages
The device provides overload and short-circuit protection with a rated breaking capacity of 6 kA and complies with IEC/EN 60898-1 standards. Its flame-retardant housing offers high temperature resistance and impact resistance. An anti-mistake contact terminal block reduces wiring errors, and the contact position indicator shows closed (red) and opened (green) states for quick visual verification.
Suitable for
Protection of single-phase circuits in residential distribution boards
Light commercial and small industrial circuits requiring selective C-characteristic tripping
Motor-fed or general-purpose circuits where 40 A protection is required
DIN-rail installations with top and bottom connections
