## Summary description

Residual current breaker HiSmart NV821952 is a protective device rated 32 A with 30 mA residual current sensitivity. Designed to detect earth leakage and quickly disconnect power to reduce risk of electric shock and fire. Suitable for residential and light commercial circuits, it provides reliable protection for personnel and equipment and is installed in distribution boards.

## Long description

Residual Current Breaker HiSmart NV821952 is a combined RCBO device with built-in overcurrent protection, designed for 4-pole installation in distribution boards. Rated for 32 A and 30 mA residual current sensitivity, it detects earth leakage and interrupts supply to reduce the risk of electric shock and fire. The unit complies with IEC/EN 61009-1 and is intended for residential and light commercial circuits.
Advantages
The HiSmart NV821952 integrates both residual current and overcurrent protection into a single compact module, saving panel space and simplifying wiring. It features anti-mistake contact terminal blocks, clear contact position indication (red = closed, green = open), and a flame-retardant housing with high temperature and impact resistance. The device is suitable for DIN-rail EN 60715 (35 mm) mounting and supports cable or pin-type busbar connections up to 35 mm².

How to use
Install the HiSmart NV821952 on a 35 mm DIN rail inside the distribution board with the connection terminals at the top. Connect supply and load conductors according to local wiring regulations, using suitable cable cross-sections up to 35 mm² or a compatible pin-type busbar. Verify correct polarity and secure terminals to prevent loose connections. After wiring, switch the device on and test tripping functionality using the test button or a suitable test device to confirm residual current operation.
Usage recommendations
Use the breaker for circuits requiring combined earth leakage and overcurrent protection. Periodically test the residual current function and inspect connections for tightness. Ensure the selected breaker characteristic (32 A, Class C, 30 mA) matches the protected circuit and local electrical codes.
