How to use

Install the HiSmart NV821419 on a 35 mm DIN rail and connect incoming and outgoing conductors to the top and bottom terminals respectively, using appropriate cable or pin-type busbar up to the specified cross-section. Ensure the breaker is mounted in an enclosure with adequate ventilation and within the specified operating temperature range. Verify the contact position indicator (red = closed, green = open) after wiring and before energizing the circuit.

Recommendations

Use this 1P 10A Class C breaker for circuits with moderate inrush currents such as lighting and general-purpose socket circuits; do not exceed the rated current and observe local wiring regulations and standards. Periodically inspect terminals for tightness and signs of overheating, and replace the device if mechanical or electrical life limits are reached.
