Contactor 230VAC 3NO+1NC 40A AC-7a/b ESC443

The 230VAC contactor with 3NO+1NC contacts and a rated operational current of up to 40A is a device that serves as a key component in many electrical installations. Its main advantage is the ability to switch high loads, making it an ideal solution for industry and advanced home and building automation systems. The use of three normally open contacts (NO) and one normally closed contact (NC) allows for flexible control configurations for various circuits.

Powered by AC voltage, this contactor has been designed to operate at a nominal working voltage from 400 to 400 V, making it perfectly suitable for use in standard power grids. Additionally, its control voltage is exactly 230 V - a value typical for most European electrical outlets.
