## Long description

Unipolar junction box HiSmart NV821785 rated 160A, designed for solar photovoltaic systems and DC power connections. It provides a single-pole connection point for cable terminations and branches in electrical distribution systems, suitable for mounting in electrical panels and on a DIN rail. The transparent cover allows visual inspection of the cable connection. The body is made of flame-retardant PA nylon and terminals are brass plated for durability and good conductivity.
Advantages
The junction box supports a nominal current of 160 A and is rated for AC/DC voltages up to 690–1000 V, making it suitable for a range of solar and DC applications. Its transparent cover enables quick verification of connections, while the flame-retardant PA housing (UL94 V0) and brass-plated terminals provide heat resistance, strong insulation and corrosion-resistant contacts. The compact dimensions and DIN-rail mounting simplify installation and wiring organization.
Suitable for
Solar PV string connections and DC combiner boxes
Connections between inverters, modules and battery systems
Electrical panels and DIN-rail mounting in industrial or commercial installations
