## Summary description

HiSmart NV821624 is a 4‑pole miniature circuit breaker rated at 32 A for protection of low‑voltage electrical circuits. Designed for installation in distribution boards, it interrupts overloads and short circuits across four conductors. Suitable for residential, commercial and light industrial applications where multi‑pole protection is required.

## Long description

HiSmart NV821624 is a 4‑pole miniature circuit breaker rated at 32 A and class C, designed for overcurrent and short‑circuit protection in low‑voltage distribution boards. It provides simultaneous interruption of four conductors and features a clear contact position indicator to show on/off status. The device complies with IEC 60898‑1 / EN 60898‑1 and is suitable for installation on a 35 mm DIN rail.
Advantages
The breaker offers overload and short‑circuit protection with a rated breaking capacity of 6 kA and an impulse withstand voltage of 6 kV. It includes an anti‑mistake contact terminal block, flame‑retardant housing with high temperature and impact resistance, and supports both cable and pin‑type busbar connections. The top‑and‑bottom connections and compact dimensions simplify wiring and installation in standard distribution enclosures.

How to use
Mount the HiSmart NV821624 on a 35 mm DIN rail inside the distribution board using the built‑in fast clip device. Connect conductors or a pin‑type busbar to the top and bottom terminals, ensuring the wire cross‑section does not exceed 25 mm² (or 18‑3 AWG for busbar). Verify correct tightening of terminal screws and observe the contact position indicator: red shows closed (ON), green shows opened (OFF). Ensure the installation is performed by a qualified electrician and power is isolated before wiring.
Usage recommendations
Use the breaker within its rated current and voltage limits; avoid environments exceeding the specified operating temperature range. For circuits with potentially high fault currents, confirm the 6 kA breaking capacity is adequate. Periodically inspect terminals for tightness and signs of overheating as part of routine electrical maintenance.
