## Long description

Residual current circuit breaker HiSmart NV821891 is a 2-pole RCBO rated for 25 A nominal current and 30 mA residual sensitivity. It combines overcurrent and earth-leakage protection in a compact device suitable for residential and light commercial distribution boards. The unit disconnects supply quickly in case of fault currents to reduce risk of electric shock and fire.
Advantages
The HiSmart NV821891 integrates short-circuit/overload protection with residual-current detection, providing combined protection in a single module. It features an anti-mistake contact terminal block, clear contact position indication (red = closed, green = open), and a flame-retardant, high-temperature resistant housing with impact resistance. The device offers a rated short-circuit capacity of 6 kA and complies with IEC 61009-1 / EN 61009-1 standards.
Suitable for
Residential distribution boards
Light commercial electrical installations
Protection of circuits with earth-leakage concerns (bathrooms, kitchens)
Circuit protection where combined overcurrent and residual-current protection is required
