## Summary description

Two-pole miniature circuit breaker HiSmart NV821662 rated for 63 A and up to 500 V DC. Designed to protect DC circuits from overloads and short circuits in industrial and commercial applications. Compact form factor for DIN-rail mounting, suitable for photovoltaic, battery storage and other direct-current installations where reliable circuit protection and simple installation are required.

## Long description

HiSmart NV821662 is a two-pole DC miniature circuit breaker rated for 63 A and up to 500 V DC. The compact, modular device is intended for protection and isolation of direct-current circuits in photovoltaic, battery storage, industrial, commercial and communication systems. It provides thermomagnetic overload and short-circuit protection and is designed for DIN-rail (35 mm) mounting with a clear contact position indicator.
Advantages
The breaker supports a rated voltage of 500 V DC and a nominal current of 63 A, with an ultimate breaking capacity of 6 kA. Modular construction simplifies installation on a standard DIN rail and the contact position indicator shows closed (red) and open (green) states. It meets IEC/EN 60947-2 standards and EU RoHS requirements, features thermomagnetic tripping, and offers compact dimensions suitable for space-constrained panels.
Suitable for
Photovoltaic (PV) arrays and solar installations
Battery storage systems and DC microgrids
Industrial DC power distribution
Commercial and communication DC circuits
