Μικροαυτόματος HiSmart NV821488 2P 10A κλάση C

Miniature Circuit Breaker HiSmart NV821488 2P 10A Class C is a compact DIN-rail mounted protective device designed to interrupt electrical circuits in case of overloads and short circuits. The two-pole breaker is suitable for single-phase or split-phase applications up to AC 400 V and provides a rated breaking capacity of 6 kA with Class C tripping characteristic for moderate inrush currents.

Advantages

The device offers overload and short-circuit protection with clear contact position indication (red = closed, green = open). It features an anti-mistake contact terminal block, flame-retardant housing with high temperature and impact resistance, and dual-sided top and bottom connections for flexible wiring. The breaker meets IEC/EN 60898-1 standards and includes a clip-on mounting for 35 mm DIN rails.
