## Summary description

HiSmart NV821907 is a residual current breaker (RCD) rated for 32 A with a 30 mA residual current sensitivity. It detects leakage currents and quickly disconnects the circuit to reduce electric shock risk and prevent fire caused by insulation faults. Suitable for residential and small commercial electrical installations to protect circuits with earth-fault protection.

## Long description

HiSmart NV821907 is a 2-pole residual current circuit breaker with overcurrent protection (RCBO) rated at 32 A and 30 mA residual sensitivity. Designed for combined protection against overloads, short circuits and earth leakage, this device disconnects circuits quickly to reduce the risk of electric shock and fire in residential and small commercial installations. The unit meets IEC 61009-1 / EN 61009-1 standards and is suitable for DIN-rail mounting.
Advantages
The RCBO integrates residual-current detection and overcurrent protection in a single compact module, saving space in distribution boards. It features a clear contact position indication (red = closed, green = open), flame-retardant and high-temperature resistant housing, an anti-mistake contact terminal block and supports cable or pin-type busbar connections up to 35 mm². The device offers a rated short-circuit capacity of 6 kA and a quick break time for fast disconnection.
Suitable for
Protection of branch circuits in residential electrical panels
Small commercial installations requiring combined RCD and MCB protection
Circuits where space-saving DIN-rail mounted protection is needed
Applications requiring 32 A rated current with 30 mA earth-fault sensitivity

How to use
Install the HiSmart NV821907 on a standard 35 mm DIN rail inside the distribution board. Make electrical connections to the top terminals using appropriate cable or busbar up to 35 mm² and ensure correct polarity and secure tightening according to local electrical regulations. After wiring, switch the device on and test residual-current operation using a suitable RCD tester or the built-in test function, following manufacturer and regulatory instructions.
Usage recommendations
Use the RCBO for final circuit protection where both earth-fault detection and overcurrent protection are required. Periodically test the device (recommended monthly) and perform professional inspection and maintenance according to local standards. Do not install in environments exceeding the specified temperature range or where ingress protection IP20 is insufficient.
