Description
The Hager HMD490 is a robust miniature circuit breaker designed for overload and short circuit protection in residential, commercial, and industrial applications. Its D tripping curve makes it suitable for handling loads with high current peaks, such as motors or industrial systems. Certified with a rated breaking capacity of up to 15 kA according to EN 60898-1 and an operating voltage of 415 V AC, it offers robustness and reliability.
Certified with rated breaking capacity (Icn) and extended short circuit capacity (Icu) both equal to 15 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.
