## Summary description

Residual current breaker HiSmart NV821969 is a protective device rated for 63 A with a 30 mA residual current trip sensitivity. It detects leakage currents and disconnects power to reduce electrocution and fire risk. Suitable for residential and light commercial electrical installations, it provides essential earth-fault protection for circuits and electrical appliances.

## Long description

Residual Current Breaker HiSmart NV821969 is a four-pole RCBO providing combined overcurrent and earth-leakage protection. Rated for 63 A with a 30 mA residual current sensitivity, the device disconnects the circuit when leakage or short-circuit conditions occur. Designed for DIN-rail installation, it meets IEC 61009-1 / EN 61009-1 standards and is intended for residential and light commercial electrical installations.
Advantages
The RCBO offers integrated overcurrent and residual-current protection in a single device, reducing the number of components required in a distribution board. It features an anti-mistake contact terminal block, clear contact position indication (red = closed, green = open), and a flame-retardant housing with high temperature and impact resistance. The breaker has a rated short-circuit capacity of 6 kA and supports cable or pin-type busbar connections up to 35 mm².
