Product information

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.

How to use

Mount the HiSmart NV821426 on a standard 35 mm DIN rail using the fast clip device. Connect supply and load conductors to the top and bottom terminals respectively, observing correct polarity and using appropriate conductor cross-sections up to 25 mm² (or 18-3 AWG for busbar). After installation, switch the breaker to the ON position; if it trips due to overload or short circuit, identify and clear the fault, then manually reset the breaker to restore power. Operate within the ambient temperature range of -5 °C to +40 °C (daily average < 35 °C).

Usage recommendations

Use the device only in accordance with IEC/EN 60898-1 requirements. Verify conductor sizes and tighten terminals to manufacturer-recommended torque values. Do not exceed the rated current or breaking capacity, and ensure regular inspection in environments with dust or corrosive conditions.
