ESC425 Hager ESC stykač 4P 25A 230VAC 4NO

The Hager ESC425 is a 4-pole installation contactor rated at 25 A with a 230 V AC control coil and a 400 V rated operating voltage. It features 4 normally-open contacts and occupies just 2 DIN rail modules, making it suitable for switching applications in building installation panels. Usage category AC-7a/AC-7b covers resistive and slightly inductive load circuits.
