## Long description

Miniature circuit breaker HiSmart NV821426 is a single-pole (1P) protective device rated at 16 A and Class C tripping characteristic. Designed for DIN-rail (35 mm) mounting, it provides overload and short-circuit protection for residential and light-commercial circuits and allows manual resetting after a trip. The housing is flame-retardant, resistant to high temperature and impact, and features a contact position indicator (red = closed, green = open).
Advantages
The HiSmart NV821426 combines short-circuit and overload protection with a 6 kA breaking capacity and a clear contact position indicator. It supports top and bottom connections for cables and pin-type busbars, accepts conductors up to 25 mm² (or 18-3 AWG for busbar), and is rated to IEC/EN 60898-1 standards. Mechanical durability and electrical life ratings (20,000 mechanical operations and 8,000 electrical operations) make it suitable for repeated use in distribution boards.
