## Summary description

Miniature circuit breaker HiSmart NV821563 is a 3-pole protective device rated at 40 A with C characteristic tripping. Designed for overload and short-circuit protection in three-phase electrical installations, it ensures reliable separation and selective protection of circuits. Suitable for residential, commercial or light industrial distribution boards where compact, DIN-rail mounting breakers are required.

## Long description

Miniature circuit breaker HiSmart NV821563 is a 3-pole protective device with a rated current of 40 A and C characteristic tripping. It provides overload and short-circuit protection for three-phase electrical installations and offers clear contact position indication. The breaker is designed for DIN-rail EN 60715 (35 mm) mounting and supports top and bottom connections for cables or pin-type busbars.
Advantages
The device combines overload and short-circuit protection with a 6 kA rated breaking capacity and 500 V insulation voltage. It features flame-retardant materials with high temperature and impact resistance, an anti-mistake contact terminal block and visible open/closed contact position indication (red = closed, green = open). Compact dimensions and standard DIN-rail installation simplify integration into residential, commercial and light industrial distribution boards.
Suitable for
Three-phase distribution boards in homes and apartments
Commercial electrical panels and small offices
Light industrial control and distribution systems
DIN-rail installations requiring compact 3-pole protection

How to use
Mount the HiSmart NV821563 onto a 35 mm DIN-rail using the built-in fast clip device. Connect supply and load conductors to the top and bottom terminals respectively, ensuring cable or pin-type busbar cross-sections do not exceed 25 mm² and that connections are tightened to the manufacturer’s torque recommendations. Verify correct phase wiring and that the device’s contact position indicator shows the expected state. After installation, test the breaker operation and coordination with upstream and downstream protection devices before putting the circuit into regular service.
Usage recommendations
Use the breaker within its rated limits (40 A, AC 400 V, 6 kA breaking capacity) and in environments with operating temperatures between -5°C and +40°C. Ensure periodic inspection and testing according to local electrical codes and replace the device if mechanical or electrical wear is detected. For installations requiring higher breaking capacity or specific selectivity, consult an electrical professional.
