## Summary description

Residual current breaker HiSmart NV821914 is a protective device with rated current 63A and residual current trip sensitivity 30mA. Designed to detect earth leakage and cut power to prevent electric shock and reduce fire risk, it suits residential and small commercial circuits. Suitable for installation in distribution boards to protect circuits and users.

## Long description

Residual Current Breaker HiSmart NV821914 is a combined protective device integrating overcurrent (MCB) and residual-current (RCD) protection in a single 2-pole unit. Rated at 63 A with C-characteristic tripping and 30 mA residual sensitivity, it detects earth leakage currents and disconnects supply to reduce the risk of electric shock and fire. The compact module is intended for DIN-rail mounting in distribution boards and is suitable for residential and small commercial circuits.
Advantages
The device provides both overcurrent and earth-leakage protection in one unit, saving space and simplifying wiring. It features a clear contact position indicator (red = closed, green = open), an anti-mistake contact terminal block, flame-retardant and impact-resistant housing, and supports top connection with cable or pin-type busbar up to 35 mm². The breaker meets IEC/EN 61009-1 standards and offers a rated short-circuit capacity of 6 kA.
Suitable for
 Protection of lighting and socket circuits in homes
 Small commercial and office circuit protection
 Installation in consumer units and distribution boards on 35 mm DIN rail

How to use
Install the HiSmart NV821914 on a standard 35 mm DIN rail inside the distribution board. Make connections from the top using appropriate cable or pin-type busbar up to 35 mm² and ensure tight, secure terminations. Observe the correct phase and neutral polarity and follow local electrical codes when wiring. After installation, test the residual-current trip function according to applicable regulations to confirm proper operation.
Usage recommendations
Use this RCBO for circuit protection where both overload/short-circuit and earth-leakage protection are required; ensure coordination with upstream protection devices and verify the device is suitable for the expected fault current and installation environment.
