Description
The Hager HMF490 is a robust miniature circuit breaker designed for overload and short circuit protection in residential, commercial, and industrial applications. Featuring 4 poles with a C tripping curve, it is also ideal for loads with moderate inrush currents such as motors or lighting systems.
Certified with rated breaking capacity (Icn) and extended short circuit capacity (Icu) both equal to 10 kA, it can operate up to 400 V AC.
Thanks to compliance with the CEI EN 60898-1 and EN 60947-2 standards, it can be installed on a DIN rail with a footprint of six modules and supports rigid conductors up to 70 mm² and flexible conductors up to 50 mm², guaranteeing high performance in demanding environments.
